I was wondering if there are a formula (or more than one) to calculate the exact amount of power of a beam that is spread in circle.
For example i make a "tunnel" with a rotating mirror with a 100Mw green laser. How can i calculate the power of a single spot on the projected circle?
Or a single spot if i make a line beam?
I think know it would be very useful about safety especially in laser shows.
