A laser pointer, also known as a laser pointer, is a portable device that uses a battery and a laser module (light-emitting diode) to emit a visible light beam.The range distance is relatively long, as an indication, but also can control PPT or Word and other documents page turning and black screen, quick play function.
The laser commonly used in the imagesetter is a helium-neon laser with a wavelength of 635nm red semiconductor laser, 650nm infrared semiconductor laser and a wavelength of 780nm infrared light.
Fiber laser doped with rare earth elements, which is mainly composed of pump source, isolator, beam combining device, doped fiber and other components.
Semiconductor laser is an optoelectronic device that can emit coherent radiation light (with the same phase, basically the same wavelength and high intensity) under current injection.
Infrared laser and ultraviolet laser have been widely used in the field of micropores. The difference in processing mode between the two makes the UV laser make up for the limitations of infrared laser very well. Infrared and ultraviolet laser applications Infrared laser and ultraviolet laser have
The application of green light laser All-solid-state lasers are developing in the direction of multi-wavelength, among which LD pumped all-solid-state green lasers are developing rapidly and are widely used in various fields. Medical applications Because the human eye is most sensitive to green l
The laser beam expander is designed to enlarge the parallel output beam of the larger diameter of the parallel input beam. Laser beam expanders are used in applications such as laser scanning, interferometry, or telemetry. Current laser beam expanders are designed with non-focus systems developed
The laser beam expander is designed to expand parallel input beams with larger diameter parallel output beams. Laser beam expanders are used in applications such as laser scanning, interferometry or telemetry. Current laser beam expanders are designed with afocal systems developed from the foundatio
In fact, the choice of green or red flashlight laser light can be based on personal preference, but if you require a longer range, I suggest that friends who require more obvious effects can choose green light, because green is the most obvious effect in the laser source RGB, which is better than th
