Principle of laser bird repellent:

For birds, vision is the most sensitive, especially for green lasers with a wavelength of 520-532nm. The laser bird repellent takes advantage of this feature. When working, the green laser simulates the condition of biological reflections. When the green laser beams over, the birds will see a big green rod to achieve the effect of repelling birds.

Birds are afraid of green light, so the strong green beam emitted from the laser transmitter is a great deterrent to "birds". When it is irradiated near the birds, the birds are frightened and flee in panic. It emits a green laser beam that can sweep runways and grasslands. This product is suitable for bird-repelling work in the evening or night in airports, orchards, farmland, warehouses, power grids, and other places.
