Lasers have huge potential for spectral applications in many aspects. They can exhibit very large temporal coherence. This is related to the narrow line width. In the extreme case of precision spectroscopy, subhertz linewidths are used. Please note that the narrow line width not only helps to improve the measurement resolution, but also helps to increase the sensitivity. For example, when applied to all probe lights, the absorption associated with a particular absorption line is easier to see, not just some spectral content. High-intensity laser 20000mw pointers have many new physical phenomena, such as nonlinear optical effects and induced Raman scattering, so I think this is a new field that has not been considered for application.
There seems to be research to make small accelerators by applying high-intensity lasers. Wavelength is a physical concept that reflects the wave characteristics of matter. All matter and energy have characteristics similar to waves and particles. The wavelength is the distance between two consecutive peaks or troughs of a wave measured in the direction of the wave. In other words, it is the distance the wave shape repeats. Lasers in red, orange, or any shade in between are the earliest types of red laser pointer. Even today, the color spectrum still contains many basic laser pointers or tools. In terms of power output, red or orange lasers are more or less harmless, but the human eye will never see them.
The 635nm red laser pointer is not as obvious as the green laser, and it is sufficient for formal demonstrations in school education, star positioning, and astronomical research. When pointing at such a low-power red laser, you don’t need to wear laser goggles. In addition, do not try to point at moving vehicles, airplanes, or airplanes, no matter what type of high powered laser pointer you are pointing at. Aim at a large laser beam that can be turned temporarily. Whenever people point to a pen-type laser device, don't hand it over to someone with bad intentions or abuse it. What are the characteristics of the 5mW red laser pointer? With a pen design, you can take your pet cat or dog anywhere. This portable laser can be put in your pocket, so you will not feel any inconvenience when carrying it outdoors. The red light is particularly dazzling, giving people the opportunity to show off in front of everyone.
