A 445nm blue laser pointer flashlight green laser pointer with a power of 1W. The appearance of the flashlight is similar to that of an ordinary flashlight, and most of them use lithium batteries. Because the laser pointer is large in size, easy to use, and the module generates heat, the power is generally greater than that of the gun laser pointer, and the power is between tens to hundreds of milliwatts, and some are even as high as 1000 milliwatts (1W). Recently, a yellow laser pointer with a wavelength of 593.5nm appeared on the market. Based on DPSS technology, 1064 wavelength 1342nm and two laser beams are added through a nonlinear crystal. Generate more narrowband lasers. Recently, a yellow laser pointer with a wavelength of 593.5nm appeared on the market. The laser pointer is a demonstration of the laser device that works with the laser device. Green laser pointers always use infrared laser diodes, which generate green light by doubling the frequency. In the case of a very cheap laser pointer, the infrared component is sometimes not filtered out, so you also have a relatively strong, invisible laser beam.
In addition, most 593.5nm laser pointers operate in pulse mode to use smaller size and power pump diodes. 808nm infrared laser nonlinear crystal excitation wavelength, 1064nm infrared light is generated, and then through frequency doubled 532nm green light, it is a solid-state laser. The green laser pointer ranges from 50mW to 150mW, and astronomy is always popular. The bright laser beam visible in the front provides a lot of convenience for astronomy researchers and astronomy enthusiasts, starry sky, and star demonstrations. Children's toy gun laser pointer guns refer to products that use lasers. The laser is stimulated by the laser beam to reflect the intensity of the laser radiation power. If the laser radiation power is too high, it will cause photochemical damage to the body and thermal damage in the developmental stage, especially for children. When the eyes and skin are exposed to laser radiation, it can be Lead to serious consequences.
