Abstract: | We present the results of the analysis of a fiber laser containing two nonlinear amplifying-loop mirrors (NALM). With the theoretical analysis we have developed, we were able to extend the analysis of a figure of eight laser (F8L) to the case of a similar structure with two NALM. Using the split-step Fourier method we have determined the influence of each NALM coupling ratio on the performance of the laser. We obtain a reduction in the fiber amplifier gain needed to initiate the oscillation as a consequence of this new configuration. Results also show that an optimum combination of the two NALMs' parameters is possible for given optical power and width of the generated pulses. |
