Picture is taken at the focal point of a PGLIII beam focused by a biconvex 50mm f.p. lens. The whole picture is 1cm in height. 40 microns is 80 wavelengths across

Guess I have to show my ignorance

Are you saying 3 times 10 to the 8th power watts per square meter ??
I'll take that in pennies !!

Incidentally, it's the same number as the speed of light in m/s.

Although now that I think about it, factoring in the power loss from the lens, it's closer to 250,000,000 W/m^2.

FN -

I knew I'd seen that number somewhere but I didn't recognize it in text format.
I can't count that high either......
