What can 50MW Blue Laser Pointer do?

The common red wavelength at 635 nm is only 27 percent brighter than 532 nm. This has a square root effect on the distance of visual interference. A 532 green laser pointer appears 4 times brighter than a 635 red laser - but the green visual interferes only 2 times from the red distance. (The square root of 4 is 2.) The common blue wavelength at 445 nm looks only 3.5 percent brighter than light at 532 nm. Again, there is a square root effect of distance. A 532 green laser appeared 29 times as bright as a 445 blue laser - but the green's visual interference was only 5.4 times longer than the blue's. (The square root of 29 is 5.4.) I knew they would be in the daytime, and if they saw a bright light sweeping through them, even if the beam line wasn't visible, they would probably fly at that power. But have to be careful, too much power in the bird's (or bystander's) eyes is bad news, if the power is too much or too close, the beam does need to have a lot of divergence (long distance) or unfocused a lot to avoid harming them with some force, I don't know what distance is safe for the birds in those terms. I know they don't like 450 nautical miles, just sweep the air in their direction at a higher power, don't even get close to hitting them (below) and they scatter. Their eyes are sensitive to ULTRAVIOLET light, so 450 nm doesn't seem dim to them, just be careful and limit the power.
