Özet

The increase of signal power through an optical amplifier generally depends on the shape of the input signal. The optimum signal beam profile in three-level amplifiers is analytically determined using a variational approach. For a Gaussian pump distribution, it is demonstrated that a high-order super-Gaussian signal is nearly optimum for a wide range of the signal to pump width ratio.
