Experimental Study on the Time-Domain Statistical Properties of Er-doped Random Fiber Laser

Er-doped random fiber laser (ERFL) is a complex physical system, and understanding its intrinsic physical mechanisms is crucial for promoting applications. In this paper, we experimentally investigate the time-domain statistical properties of ERFL under full-bandwidth condition for the first time. We also study the effects of the transmission process and Raman amplification process on the output characteristics of ERFL.
