It will be used to scare away pidgeons relatively far away. The more power the more of a impression it will make.
Used because its cheaper.

18650 powered would be great but not a requirement. 532nm is a requirement because DPSS has a tighter/brighter beam.

Please pm, thanks!

Shipping will be to germany.

"Birds' vision is tetrachromatic: Most have long-, medium-, and short-wavelength cones similar to those of humans, but in addition have a cone type enabling them to detect wavelengths in the near ultraviolet range (300–400 nm)"

Id opt for a beefy 405nm with beam expander given 4 factors,

1-they see near UV very well
2-405 is far more stealthy and attracts less unwanted attention.
3-if im not mistaken, you'll achieve greater range given the lower divergence
4-reliability and stability over temperature variation

Thanks, i have researched and saw that as well. Practicality goes first, but Im pretty sure that over 1watt of 532nm will also scare them away, plus that I had concerns about the visibility of ultraviolet during daylight. No idea what is perceived as brightest to doves, but during bright sunlight being able to scare them away is also important. Birds may be able to see the 300-400nm laser better then humans, but during sunlight the brightness perceived will probably diminish, and we dont know what wavelength is brightest to them.
Plus, with 532nm we humans can also have fun with stargazing, burning and other stuff. But yeah, sacrificing stealth in return.

I have bought a jetlasers 1300mW 532nm laser. This thread can be closed.
