The two characteristics of good directivity and good monochromaticity of laser can also be used for communication. Everyone knows a very great thing from the last century. It is optical fiber communication. In addition to fiber-optic communication, free-space communication is also possible. In recent years, quantum confidential communication has appeared, and lasers have also been used. The laser TV is composed of a laser pointer light source projector and a projection screen using reflective ultra-short throw projection technology. It can show a good picture even in a bright environment.
So what effect (if any) does the color of the light beam have on the combustion power? Because the burning ability of a laser depends on its power and the amount of heat it can generate, there will be no difference in color (but it is important to note that a 532nm green laser is 7 to 10 times brighter than any other color laser). In fact, infrared lasers that are invisible to the naked eye can burn like a transparent green laser pointer of 5000mW when the correct output power is 5000mW or higher.
When you choose the power output color and beam, you will need to consider different functions. If you are looking for this kind of function, you should look for a model that can adjust and focus the burning beam. Now this is not necessary for burning lasers over 200mW, but it will help edge lasers to be more suitable for burning lasers, and also increase the burning power because you can adjust the beam. hot.
