How can it become a burning laser pointer kitu?

This is the most important factor (rather than beam color) to determine whether a single laser pointer is a burning device. Today's Laser pointer can go from less than 5mW to 5000 mw or 5W. This means knowing where the combustion threshold is, which is usually at least 100mW. This means that any laser pointer below 100mW is very difficult to burn anything, and will not be able to do it. Any laser over 100mW will be considered a combustion device, but not all lasers are the same. The higher the mW power, the greater the burning capacity, so if 100mW of power can only break a black balloon and light a match, it will not be able to cut the tape. You need 500mW or higher power to really get the maximum burning capacity. The higher the power, the better the distance and burning effect. An anti-falling sleeve made of soft material is arranged on the barrel of the burning laser pointer, and the anti-falling sleeve is formed by inserting a pen barrel anti-falling sleeve and a pen cap anti-falling sleeve into each other. Compared with ordinary laser pointers, laser pointers with anti-drop sleeves not only have ordinary writing and beam pointing functions, but also have anti-drop functions. During use, if you accidentally fall on the ground, it will not be broken, which is beneficial to protect and play the laser. The function of the pen is an indispensable combination tool for ordinary writing and multimedia teaching screen beam commands.
