Green laser pointer can be used illegally
If you can actually control the desired beam width, you can aim at distant objects more accurately. A beam aimed for a few miles widens as it moves outward, so being able to narrow the beam allows you to maintain a tighter beam over a longer distance. It reduces divergence and is ideal for a variety of applications. Reverse the focus of the head. After removing the cover, you can rotate the top of the green laser pointer body. By twisting the head, the laser beam lines will change and cross each other. Now find the intersection of most laser beam lines, which is the best combustion position. There are numerous reports criticizing the harm of high-power laser pen to human body. I insist that anything that can burn is at the same dangerous level. Ordinary lighters or knives are also harmful to human body, but that doesn't mean people shouldn't use them. These tools, powerful electric tools will bring greater danger. Before using combustion tools, the correct practice is the most important.

In fact, any laser indicator crow can be used, but the difference is that 532nm green laser is the brightest color of human eyes, and green laser is 5-10 times brighter than any other laser color... Therefore, 100MW green is much brighter than 100MW blue, red or purple laser. In addition, this bird repellent is carried out during the day, so you need as bright a color as possible. Otherwise, the herd will not be significantly affected. If a very low output power is selected, the laser beam cannot be seen at night and during the day. The beam of 532nm green laser pen up to 30MW is clearly visible. During the day, you can even see the green laser beam indoors. A laser indicator with a higher output power produces a stronger and stronger green laser indicator beam.
