title: Cascaded random distributed-feedback Raman fiber laser assisted by Fresnel reflection.
abstract: We propose a new type of cascaded random distributed- feedback Raman fiber laser (RD-RFL), with the linear output at the second-order Stokes wavelength. The guideline about building such a RD-RFL with particular output power and conversion efficiency is presented based on numerical study. We also experimentally instantiate the principle, and confirm the effectiveness of the scheme on lasing generation. Moreover, the added Fresnel reflection feature maintains the simplicity and flexibility of the RD-RFL.
