What is the electric field strength of the laser light at the focus point?
A LASIK vision correction system uses a laser that emits 10ns long pulses of light, each with 2.5 J of energy. The laser is focused to a 0.90 mm -diameter circle.
Alright, that makes sense but the answer is supposed to be in N/C. So how would I do that?
Intensity I(peak) = energy/(area*time) = 9.82438E13 W/m^2
E = sqrt(I(peak)*Z0) = 192383516.88676 V/m
(where free-space impedance Z0 = sqrt(ยต0/e0) = 376.730313462204 ohms)
