What is the proper method for focusing a high power laser?
I recently finished up my first 445nm 1W build. However, I'm not entirely sure how to focus it for the least divergence. I assume the best way to go about it is to simply adjust it a little, turn it on, check divergence, turn it off, adjust, check, etc... This is probably a total noob question. I just don't want to be sticking my hand near the aperture while the laser is on and causing damage to my eyes with diffuse reflection.
Also, how do I know when I've got it as good as I can possibly adjust it?
