What is the power of the green laser pointer used for demonstration?
The low-power 5mW green laser pointer can project a strong laser beam and emit visible light at night through the Rayleigh scattering of air molecules. For example, astronomers usually use a 5mW green laser pointer to indicate stars, constellations, and other celestial bodies in the sky. Simply press the button to activate the green laser pointer, then release it to deactivate it. Use your green laser pointer to point to any target on the canvas or video. The sky full of stars allows you to find the stars you want in the fascinating sky, and is a guide in the vast sky. The laser pointer is very well made, is located very comfortably in the hand, and is provided with a metal case for storage. I use it professionally and I am very satisfied with it. Therefore, it is recommended to use only Class 1 and Class 2 laser pointers. The maximum intensity of these two types of laser pointers may be 1 milliwatt (mW). You can build a powerful 500mW green laser pointer by replacing the 500mW green laser pointer from the laser pointer diode and laser diode parts supply store, thereby removing the restrictions on electronic products.

Only lasers below level 2 are considered harmless (see also hazards and health risks). The police are looking for witnesses who saw someone using a 1 MW laser on Tuesday night. Kripo is investigating dangerous interference with air traffic. The perpetrator faces up to ten years in prison, but she pointed out how dangerous this behavior is. In the past, strangers have used laser pointers many times. Lightweight and portable design, it is very convenient to put it in a pocket or pocket. This pen is small and exquisite, convenient to carry, and has a wider range of uses. Regarding the burning power of the laser pointer, the most important item is the power output. Hand-held high powered laser have low power below 5 mW and civilian lasers up to 5,000 mW (5 watts). But what is the appropriate power to generate enough heat to be considered a "burning laser"?
