Laser Peak Power Calculator

Use this calculator to determine the peak power of your laser beam.

Laser Parameters



  1. This calculator assumes square pulses. For other shape pulses, the result will not be completely accurate. (You can see your precise laser pulse shape with a fast photodiode like the FPS-1)
  2. Tophat calculations are for ideal tophat laser beams.
    For beams that are not 100% uniform, the peak power/energy density will be higher.
  3. Gaussian beam intensity is calculated for the 1/e^2 (13.5% of peak) beam diameter.
