Özet

The effect of the Erbium gain on the Stokes signal performance is experimentally presented in this paper. Linear Brilllouin Erbium fiber laser cavity is tested under different 1480nm pump power ranges (0-125mW). Different Brillouin pump (Bp) power values of 2, 4 and 6dBm are used in this study. Stokes signal net gain and threshold power are recorded at all generated Stokes signals for these Bp powers values. 2dBm Bp power shows higher net gain, low threshold, large Stokes numbers and low required 1480 nm pump power compared to 4 and 6dBm. Up to 8.3dB net gain, threshold of -10.3dBm, 24 Stokes signals and with a maximum 1480nm pump power of 92.2mW are recorded for 2dBm Bp power. Stokes signal threshold is recorded at the near end of the single mode fiber at which Nth order Stokes is generated.
