So I've read quite a bit about corrective optics and they seem to be the golden solution (for now at least) to horrible divergence in high powered lasers, but why aren't they more popular/more commonly used?
I was reading this thread in particular about a guy who used corrective optics to make his NUBM44 laser have an insane divergence of .35mrad with a beam diameter of 6mm. The dot at 10m away was only 1cm long. This is a quote from that thread that the guy stated after finishing this project,"I feel like this is it now. I never had a laser with below 0.9mRad divergence, and now, ironically, it is coming out of the most diverging and the most powerful diode we have for this hobby. Its amazing." So again, why don't more people do this with the NUBM44s and other high powered diodes???
