Can laser pointers really deter animals?

You can't just use any laser to do this kind of thing. The nature of the condensed laser beam is very different from day or night. You can't control when the goose will come. They usually nest at dusk, and you need a laser strong enough to use in the sun. But not all lasers are suitable for daytime use. You need no less than 400mW of 532nm green light to be suitable for hundreds of feet. The general rule is "the higher the power, the better the effect during the day." This green line laser is aimed at a projected laser beam with a particularly uniform distribution of non-Gaussian light. The laser fan angle can be customized. This advanced alignment laser is widely used in industrial equipment, precision processing, measuring equipment, image processing systems, and textile processing. The U.S. Department of Agriculture estimates that there are about 300 vultures living on the Granville and Denison campuses. In addition to interfering with HVAC projects and different machines, it can also cause damage to the roof.
