### Power density of laser beam Calculator

Power density of laser beam Solution. STEP 0: Pre-Calculation Summary. Formula Used. Power Density of laser beam = (4*Laser Energy Output)/ (pi*Focal length of lens^2*Beam divergence^2*Duration of laser beam) PD = (4*P)/ (pi*f^2*α^2*ΔT) This formula uses 1 Constants, 5 Variables. Constants Used. pi - Archimedes' constant Value Taken As 3 ...
