Calculation Formula

Optical Gain (G) = (Pump Power / Saturation Power) * (1 - exp(-Small-Signal Gain * Length))

Where:
G = Optical Gain
Pump Power = Input pump power in watts
Saturation Power = Power at which gain becomes equal to small-signal gain
Small-Signal Gain = Gain without saturation effects
Length = Length of the gain medium

How to Use the Optical Gain Calculator

  1. Enter the pump power in watts (W).
  2. Enter the small-signal gain in meters inverse (m^-1).
  3. Enter the saturation power in watts (W).
  4. Click the "Calculate" button to compute the optical gain.
  5. The result will be displayed in the "Optical Gain (G)" field.

Working Principle

The optical gain of a laser amplifier is influenced by the pump power, small-signal gain, and saturation power. The formula used to calculate the optical gain is:

Optical Gain (G) = (Pump Power / Saturation Power) * (1 - exp(-Small-Signal Gain * Length))

This formula accounts for the exponential decay of gain in the presence of saturation effects. The length of the gain medium is assumed to be 1 meter for simplicity.
