**DrBob222**, Saturday, February 4, 2012 at 9:02pmPlease clarify Mu. Is that 6.0 microns = 6.0E-6 meters? If so then

joules = hc/wavelength

joules = 6.626E-34 x 3E8/6E-6 = about 3E-20 J but you need to do it more accurately. Then

3E-20 J/photon x # photons = 22.5 J in 1 sec.

Solve for # photons.
