Abstract :
The influence of amplifier gain saturation in nonlinear amplifying loop mirror on simultaneous phase-preserving regeneration of two power states has been studied. Numerical simulations have shown an improvement of up to 4 dB for the first, low-power state and 8 dB for the second high-power state. Compared to the linear amplifier case an improvement of 3 dB for the second power state has been achieved.
