Calculation Formula

Pulsed Laser Average Power (P_avg) = Pulse Energy (E) × Repetition Rate (f)

Where:
P_avg = Average Power (Watts)
E = Pulse Energy (Joules)
f = Repetition Rate (Hz)

How to Use the Calculator

  1. Enter the Pulse Energy in Joules (J).
  2. Enter the Pulse Duration in seconds (s).
  3. Enter the Repetition Rate in Hertz (Hz).
  4. Click the Calculate button to compute the average power.
  5. The result will be displayed in Watts (W).

Understanding the Formula

The average power of a pulsed laser is calculated by multiplying the pulse energy by the repetition rate. This gives the total energy delivered per second, which is equivalent to the average power.

Example Calculation

If a laser has a pulse energy of 10 Joules with a repetition rate of 1000 Hz, the average power would be:

P_avg = 10 J × 1000 Hz = 10,000 W (10 kW)

Applications

This calculator is useful for:

  • Designing and analyzing laser systems
  • Optimizing laser processing parameters
  • Comparing different laser systems
  • Ensuring safety and component ratings are appropriate for the average power
