STIMULATED RAMAN SCATTERING FIBER LASERS
Physical principles, design and properties of Raman fiber lasers are considered. A mathematical model has been presented for numerical simulation of lasers with a cavity formed by photo-induced fiber Bragg gratings. Experimental results have been given for SRS lasers on silica-based optical fibers co-doped with germanium oxide, phosphorous oxide as well as combinations of such fibers. It has been shown that the stimulated Raman scattering can be used to create light sources at any given wavelength in the spectral range from 1.1 to 2.1 mm.
