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**

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

**P _{peak} = P_{avg} * T/dT**

Root-mean-square or RMS power formula is

**P _{RMS} = 0.7071 * P_{peak} **
