How does the laser pointer drive away crows?
The recent crow-killing laser pointer seems to be weaker than before, because the light hits the eyes and there is a danger of eye damage, but when the red light is aimed at the crow's eyes, the crow will run away in surprise. I heard about it. When I took out the rubbish in the morning, the crow came and it was difficult for me to disperse the rubbish. I use a broom to get rid of it, but I don't mind if I don't come close. Can't use a laser pointer? Is it cost-effective, portable, and low power consumption? Most gun pointers are semiconductor lasers (LD). Compared with other excitation lasers, it is very small and inexpensive, and it can use a power source similar to a dry battery, so it is easy to operate. In addition, it has less heat generation and good stability.

The laser will hurt your eyes and should not be aimed at the eyes of people and animals. However, the output of the 50mW blue laser pointer used in the meeting is very low, less than 1mw, just a glance. Can be used to drive away crows, extinction is cruelty to animals. Driving away is not abuse. It seems that various things are being considered, such as playing the sound of the crow's alert dialogue through the speaker, but since the crow is a smart bird, it will soon be discovered. I think it is effective to use a bird like an eagle, but it is usually difficult. Lasers are regulated by law. If you use it carelessly, you will be punished. The man who glowed toward the plane and held it was on the news.
