Theoretical analysis of fiber laser amplifiers for four-level system
Amplification characteristics of four-level fiber amplifiers are analyzed using four-level system rate equations. The relations of the signal gain against fiber length, doped ion concentration, pumping power and signal power are obtained and calculated.
