How to Calculate Power Density of Laser Beam?
Power Density of Laser Beam calculator uses Power Density of Laser Beam = (4*Laser Energy Output)/(pi*Focal Length of Lens^2*Beam Divergence^2*Laser Beam Duration) to calculate the Power Density of Laser Beam, The Power Density of Laser Beam formula is defined as the power contained in per unit area of beam cross section. Power Density of Laser Beam is denoted by δp symbol.
How to calculate Power Density of Laser Beam using this online calculator? To use this online calculator for Power Density of Laser Beam, enter Laser Energy Output (P), Focal Length of Lens (flens), Beam Divergence (α) & Laser Beam Duration (ΔT) and hit the calculate button. Here is how the Power Density of Laser Beam calculation can be explained with given input values -> 0.000949 = (4*10.39)/(pi*3^2*0.001232^2*10.2).
