Hi! I hope this thread is considered as laser measurements. Okay, so I'm trying to get intensity of the EMW (laser) with formula I=P/A power/ area.
know knowing this, i have 100mW cylindrical/ circular beam of laser so A=pi*r^2. now how in the H should i know what my radius is?
I've searched for methods to measure laser beam diameter, aperture method and the knife edge technique and also burning plates. I can't do any of these options since i have no good devices for these stuff and my laser 100mW can't burn plates! *made in china, output is not really 100mW* Any ideas how? thanks!
