The Raman random fiber laser (RRFL) is a typical complex physical system due to the
intrinsic random feedback of the fiber, which causes complexity in the RRFL output. So far …

The optical feedback in random distributed feedback Raman fiber lasers is due to extremely
weak Rayleigh backscattering, nevertheless it is capable of forming localized spectral …
