Can bird chasing laser pointer be used to repel birds?
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. Therefore, at the same output power, the brightness of the green laser will be 5 to 7 times higher than that of any other color laser. Therefore, the brightness of 200MW green 532nm laser indicator will be 7 times higher than 200MW 405nm purple laser and 5 times higher than red or blue laser.

If you have ever worked in the green laser pointer market, you may be familiar with the fact that a laser with a certain intensity or higher has a certain combustion ability. When you choose the output power and beam color, you will need to consider different functions. If you are looking for engraving ability, you should look for a model with adjustment and adjustment ability. Focus the beam. Now this is not necessary for a thermal laser, because anything higher than 200MW, but it will help the edge laser to be more used as a thermal laser and increase the combustion capacity, because you can adjust the beam to condense and increase the heat. In winter, his colleague GERD Kaufman spent several nights on the playground and other places in the city center, scaring away the birds with a laser pen. Now those in Puntigam may have "moved" to the Central Cemetery. The cemetery keeper called Moser for help. "But when it comes to shooting, our hands are tied to cemeteries: on the one hand, all hunting is prohibited in cemeteries, on the other hand, cemeteries are inhabited areas," Moser said. Therefore, we must abide by the law and are not allowed to feed crows.
