Peak Power Calculator

This calculator is used to find the Peak power of an Optical or RF pulse. It also gives the RMS power.

In the picture below, the Pulse Width is dT and it repeats with a period T

Peak and Average Power

The duty cycle is the fraction of time for which the pulse is On. Mathematically it is computed as the ratio dT/T. If the pulse has a width of 0.1 second and repeats every 10 seconds, the duty cycle is 0.01 or 1%.

Use the tool below to calculate the Peak power. Enter

  • Average power,
  • Pulse width and
  • Pulse repetition time

The peak power formula is

Ppeak = Pavg * T/dT

Root-mean-square or RMS power formula is

PRMS = 0.7071 * Ppeak
