모모The heat loss of the laser diode (LD) accounts for more than 50% of the total power consumption during normal operation, and the instability of the working temperature of the laser diode caused by the heat loss will change its output wavelength, which will affect the efficient and stable output of the DPL.

　　Laser pointer, a seemingly ordinary gadget, but you know what? They can cause damage to the camera. Let’s explore this question and how to avoid this potential risk.pass high powered laser pointer It can be seen from the present situation that the market prospect is relatively broad, which is conducive to our reference and investment. https://highpowerlaser.shop/collections/burning-laser

　　The essence of a laser is a highly concentrated beam of light with considerable energy. Although the power of the laser pointer is relatively low, it can still cause damage to the camera’s sensor if it is directly irradiated to the camera lens.

　　Irradiating a laser beam may cause damage to the sensor or even disable the camera. In indoor or outdoor environments, there is a potential risk as long as the camera is exposed to the laser beam.

　　For a better understanding, we can analyze the effect of lasers on cameras from a scientific point of view. Lasers have a high energy density, and photons are able to generate heat on the lens and sensor. This heat can damage the sensor’s structure, leading to a decrease in image quality or even malfunction.

　　According to multiple experimental reports on the Internet, the degree of damage to the camera caused by the laser pointer is related to the intensity of the laser and the irradiation time. Generally speaking, the power of ordinary laser pointers on the market, such as the one used for presentations, is usually around 5 milliwatts, and it will not cause much damage to the camera in a short time.

　　But if it’s a higher-powered laser pointer, such as a 3B-like laser, they generate enough heat to damage the camera after a long period of exposure.

　　So, if you accidentally shine a laser pointer on the camera, don’t worry too much, a brief contact is unlikely to cause permanent damage. But to be on the safe side, try to avoid this as much as possible.

　　However, this doesn’t mean that all cameras will be affected to the same extent. The material, design, and manufacturing quality of a sensor can affect its resistance to lasers. For example, some surveillance cameras may be equipped with special lenses or filters that are used to attenuate the effects of the laser beam, reducing the risk of damage.

　　To protect your camera, there are a few simple precautions you can take.

　　First of all, when using the laser pointer yourself, try to avoid shining the beam directly on the phone camera. Secondly, if you notice someone using a laser pointer (the same is true for spotlights on stage and concerts), especially near the camera, put away your phone in time and stop shooting directly to avoid potential dangers. Finally, when not using your phone, use a phone case or cover to protect the camera lens from the laser beam.

　　In practice, although laser pointers may have some impact on the camera, taking proper precautions and using them with caution can effectively reduce the potential risk of damage.

　　The above is an analysis of the damage that a laser pointer can cause to the camera. Do you understand? Feel free to leave a message in the comment area.

　　Laser pointer, also known as laser pointer, pointer, etc., is a pen-shaped emitter designed to be portable, easy to hold in the hand, and processed into a laser module (diode). Common laser pointers include red (650-660nm), green (532nm), blue (445-450nm), and blue-violet (405nm). It is usually used by newspapers, teachers, and docents to project a point of light or a ray of light directed at an object.As it happens, many people are killed purple laser And bring more benefits, make it flourish, and promote the industry greatly. https://highpowerlaser.shop/collections/frontpage

　　A physical picture of a common laser pointer

　　Early laser pointers (HeNe) HeNe gas lasers produce a laser wavelength of 633nm, typically 1mW. The cheapest laser pointers use a deep red laser diode with a wavelength of nearly 670/650nm. Slightly more expensive with red, orange 635nm diodes. Other colors are also possible, with the green laser at 532 nm being the most common alternative. Later, an orange-yellow laser pointer with a wavelength of 593.5 nm appeared. In 2005, a 473nm blue laser pointer appeared, which was introduced in September. At the beginning of 2010, a blue-violet laser pointer with a wavelength of 405 nm appeared.

　　The brightness of the laser beam on the spot depends on the laser power, the reflectivity of the surface. For the same power, the spectrum of the human eye in the green region (wavelength 520-570nm) is most sensitive and appears to be brighter than other colors. The sensitivity of the wavelength of red or blue decreases.

　　A laser pointer that typically represents the output power of milliwatts (mW). In the United States, lasers are classified by the National Standards Institute and the Food and Drug Administration (FDA). Visible laser pointers (400-700nm) operate at less than 1mW of power, Class 2 or II, visible 1-5mW laser pointers, are Class 3A or IIIa. Class 3B or IIIb lasers produce 5 to 500 mW; Class 4 or 4 lasers produce more than 500mW. The U.S. FDA regulations state that “demonstration laser products” must meet applicable requirements for Class I, IIA, or IIIA devices.

　　Measured laser map

　　Red and orange laser pointers

　　This is the simplest laser because there are red diodes. No more than one battery-powered laser diode. The first red laser pointer, released in the early 80s of the 20th century, sold for a few hundred dollars. Today, they are much smaller and generally cost very little. Diode-pumped solid-state (DPSS) red lasers at 671nm are common.

　　Yellow laser pointer

　　Yellow laser pointers are extremely rare in the market. DPSS technology is obtained by adding two laser beams with wavelengths of 1064 nm and 1342 nm through a nonlinear crystal. The complexity of the process makes the yellow laser pointer unstable and inefficient, with an output power of 1-10mW depending on the temperature, and a pattern jump if it is overheated or too cold. This is because the size of the laser pointer does not provide the required temperature stabilization and cooling parts. In addition, most 593.5nm laser pointers operate in pulsed mode to allow for the use of pump diodes with smaller size and power.

　　Green laser pointer

　　The nonlinear crystal is excited by an infrared laser with a wavelength of 808nm to produce 1064nm infrared light, and then 532nm green light is generated by frequency doubling, which belongs to solid-state lasers. Some green lasers operate in pulsed or quasi-continuous mode to reduce cooling problems and extend battery life. Green lasers, which do not require frequency doubling, have higher efficiency. At night, even low-power green light can be seen due to Rayleigh scattering of atmospheric molecules, and this laser pointer is often used by astronomy enthusiasts to point to stars and constellations. Green laser pointers can have a variety of output powers. The 5mW (IIIA) is the safest to use and is also visible in dim lighting, so no more power is required for pointing purposes.

　　Blue light laser pointer

　　Blue laser pointers such as a specific wavelength of 473 nm usually have the same infrastructure as green lasers. Many factories in 2006 began to produce blue laser modules, mass storage devices, these used laser pointers. This is the type of equipment that pumps the frequency doubling with semiconductors. They most often emit 473 nm, which is doubled by a frequency multiplied by a diode-pumped laser at 946 nm ND:YAG laser or yttrium neodymium vanadate crystals. The BBO crystal with high output power is used for KTP crystals as a lower power doubling.

　　Visible wavelength green laser pointer

　　Some manufacturers are selling indicators of parallel blue laser diodes measuring power over 1500 milliwatts. However, since the claimed power of the “laser pointer” product also includes infrared power (only in semiconductor pumping technology) is still in the beam (for reasons discussed below), the laser is still problematic on the basis of the DPSS-type elements of the more strict visual blue, and is usually not applicable. Due to the use of higher neodymium harmonics, the frequency doubling conversion efficiency is low, and the infrared power is a small fraction of the optimal configuration of the semiconductor pump module, and the conversion of a blue laser at 473 nm is typically 10-13%, which is about half of that typical of green lasers (20-30%).

　　The blue laser can also directly fabricate indium gallium nitride semiconductors, producing frequency-grabby blue light. There are blue laser diodes on the market (447＼5 nm), and the device is a bright same violet laser diode with a power of less than 405 nm, because the longer wavelength is closer to the peak sensitivity of the human eye. The mass production of laser projectors for commercial equipment, such as laser diodes, has driven down prices. The use of popular high-power (1W) 447 nm indicators, which also have improved optical versions of better collimation and lower divergence, comparable to the use of these portable devices, has reduced the sensitivity of green lasers with the intention and cost of human harm.

　　INTRODUCTIONOn the other hand, high power laser It also brings tangible benefits to everyone and feels useful. It is a model of the industry. https://highpowerlaser.shop/collections

　　Since the birth of the laser in 1960, achieving high output power has been one of the eternal themes in the development of laser technology. The process of increasing laser energy is always accompanied by thermal energy, and thermal energy is useless in this process, “laser energy” and “thermal energy” are the highest and lowest quality forms of energy respectively, and the history of the development of high-power laser technology is a history of struggle with “waste heat”.

　　The first ruby laser[1″ target=_blank> that marked the birth of lasers in 1960 was a solid-state laser. Solid-state lasers usually use activated ion-doped crystals, ceramics and glass as the gain medium, and their gain medium forms include conventional bulk materials and low-dimensional materials represented by optical fibers. After the birth of solid-state lasers, on the one hand, the wavelength coverage was expanded, from the initial red light to short-wave green light, blue light, ultraviolet, deep ultraviolet development, long wavelength

　　Lasers have matured and commercialized in the near-infrared and mid-infrared bands, and on the other hand, the laser pulse width has been narrowed from microseconds (μs) to nanoseconds (ns), picoseconds (ps), and femtoseconds (fs), and attosecond (AS) lasers are expected to be engineered [2-3″ target=_blank>. The realization of high output power in any application scenario is the common goal of laser technology development [4-6″ target=_blank>.

　　With the increase of pump power, the thermal effect inside the gain medium is significantly enhanced, and the heat generated cannot be removed from the medium in time through heat conduction, resulting in an increase in the internal temperature and temperature gradient of the medium, and the thermal lensing effect and stress birefringence effect caused by the internal thermal distortion seriously deteriorate the beam quality and limit the further increase in power [7″ target=_blank>. In order to suppress the thermal effect, researchers have designed different types of solid-state lasers, such as heat-capacity lasers, thin-slice lasers, slat lasers, and fiber lasers [8″ target=_blank>, with the core idea of improving heat dissipation efficiency. In this paper, the working characteristics and research progress of the above solid-state lasers are briefly reviewed. In addition, based on the current theoretical and experimental research on the thermal conductivity (κ) of crystalline materials, from the perspective of improving the thermal conductivity of gain dielectric materials, the thinking and prospect of solving the thermal effect problem are proposed.

　　1 High-power lasers

　　1. 1 heat capacity laser

　　Heat-capacity lasers reduce the thermal distortion of gain materials by separating the working phase of the laser from the heat dissipation phase in time. When the heat capacity laser is working, the gain medium is in an approximately adiabatic environment, and its internal temperature gradient is small, and the resulting thermal distortion is also small. The internal accumulation of waste heat increases the temperature of the gain medium, which must be forced to cool after a period of continuous operation, depending on the thermodynamic properties of the material itself. Because the gain medium does not dissipate heat from the outside during the laser operation stage, its surface temperature is higher than that inside, and the compressive stress on the surface can greatly increase the damage threshold of the medium, and the allowable laser pumping strength is 5 times that of the surface in the state of tension. The output of a heat-capacity laser depends on the product of the gain medium and the temperature range of the laser that it can generate, so it is not only required that the gain dielectric material have a large heat capacity value, but also that the luminescence efficiency of the internally activated ions is less affected by the increase in temperature [9″ target=_blank>.

　　As early as 1994, Walters et al. [10″ target=_blank> used a heat-capacity laser with flash-pumped rod-shaped neodymium glass as the gain medium to achieve a pulsed laser output with an average power of more than 1 kW and a duration of several seconds, proving the feasibility of the heat-capacity laser scheme. Subsequently, the Lawrence Livermore national laboratory (LLNL) in the United States used large-size Nd3+｜Glass, Nd3+｜Gd3 Ga5 O12 (GGG) crystals, and Nd3+｜Y3 Al5 O12 (YAG) ceramics as the gain medium to carry out the research of solid-state heat-capacity lasers (see Fig. 1) [11″ target=_blank>: In 2001, LLNL used flash lamps to pump 9 pieces10 The cm〜10 cm Nd3+｜Glass obtained a pulsed laser output with an average power of 13 kW. In 2004, LLNL used a laser diode array to pump four 10cm〜10 cm Nd3+:GGG crystals to achieve 45 kW laser output. In 2006, LLNL used a laser diode array to pump five 10 cm 〜 10 cm Nd3+:YAG ceramics with an output power of up to 67 kW and a pulse duration of 500 ms. By introducing a real-time adaptive optical correction system in the cavity, the beam quality control was within 2 times the diffraction limit, and the laser running time was increased to 5 s [12″ target=_blank>.

　　Heat-capacity lasers have two important limitations: (1) the laser beam quality degrades rapidly with the increase of light generation time [13″ target=_blank>; (2) The cooling time of the gain medium accounts for 80% of the entire working cycle, which determines that the heat capacity laser cannot work at high frequency, and the working time in seconds is difficult to meet the practical requirements.

　　1. 2 thin-slice lasers

　　The gain medium of the thin slice laser is a thin sheet with a thickness of less than 1 mm, which is fixed to a rigid substrate that dissipates heat by solder, and the bottom surface of the contact acts as a cooling surface and also acts as a reflective surface for the laser and pump light, and the other side acts as a high transmission surface. Since the direction of heat flow and the direction of laser propagation are basically the same, the wavefront distortion caused by the temperature gradient can be largely ignored, resulting in a high beam quality laser output. The advantage of thin-slice lasers is that they maintain high beam quality at high power outputs. Thin-slice lasers are available in two types of pumping methods: end-pumping and side-pumping, as shown in Figure 2 [14″ target=_blank>.

　　Due to the short propagation distance of light in a single sheet, the gain capacity is limited, and the maximum output power is currently 5 kW [15″ target=_blank>, and further power increases require the cascade of multiple lamella for amplification (see Figure 3 [16″ target=_blank>). In 2000, Stewen et al. [17″ target=_blank> achieved a continuous laser output of 647 W in a single Yb3+｜YAG thin slice by end-pumping, and a maximum laser output of 1070 W by combining four thin slices. In 2009, the Boeing Company pumped 10 Yb3+:YAG thin slices to obtain a laser output of 28 kW, with a laser duration of several seconds and a beam mass close to the diffraction limit [18″ target=_blank>. The commercial thin-slice laser developed by Trumpf in Germany is capable of producing a continuous laser with a stable output power of 18 kW. Theoretical calculations show that the maximum output power of a single sheet is about 30 kW [15″ target=_blank>, and it is clear that the current experimental results are still quite far from the theoretical value.

　　At present, the main problems of thin slice lasers are: (1) high requirements for crystal thin slice processing and welding process; (2) The gain capacity of a single sheet is limited, and the cascade of multiple pieces will make the optical path of the system extremely complex, which requires high precision assembly and adjustment ability of the system.

Researchers are constantly innovating and exploring new materials and design techniques that allow lasers to have higher power output while minimizing energy consumption. These advancements have not only improved the performance of laser pointers, but have also aided in the development of fields such as telecommunications, holography, and medical applications.

　　Advantages and disadvantages of different laser power outputs

　　When buying a laser pointer, it is essential to consider the power output, as it determines the brightness and potential hazards of the device. While a 5mW laser pointer is suitable for most general applications, higher power laser pointers, such as those with an output of 100mW or higher, provide greater brightness, range, and visibility. However, as the output power increases, so does the risk of eye injury, so extra precautions must be taken.

　　In conclusion, disassembling the 5mW green laser pointer gives you a glimpse into the inner workings of these handheld devices. Thanks to the focus on security measures and the desire to explore the intricacies of technology, the process is both educational and rewarding. Understanding the functions of laser pointers and the role they play in various fields helps us understand the advancements in laser technology and their impact on our lives.
