A class 1M laser can go up to 500mw of power(I think higher if they are pulsed and most IR diodes are pulsed), now from my experience with IR lasers the all have horrible beam divergence and its near impossible to focus them.
I stand corrected on the Class 1 vs. Class 1M. By the nature of the task, I knew that they had a widely diverging beam. So it seems like we will need a high peak power and leave the beam diverging.
ALL laser diodes visible or near-infrared have high divergence. It's just the optics that are put on them that can tame it. I have used plenty of NIR LDs that have very collimated beams due to a nice aspherical optic in front of them.
I'd be really surprised if cops were shooting 50W peak lasers, even pulsed. If they got scatter off their cars window frame, they run the risk of serious eye damage.
Anybody have a p/n of the laser inside a LIDAR?
