Flatness Investigation of Multiwavelength SOA Random Fiber Laser Based on Sagnac Loop Mirror
We investigated the lasing performance of multiwavelength random fiber laser (MWRFL) at different single-mode fibers (SMFs). The main investigation is based on 700 m SMF with the presence of highly nonlinear fiber (HNLF) and polarizer as the current of the SOA is set to the maximum which is at 900 m...
