We report using a Raman fiber laser (RFL) based on a multimode graded-index fiber as a novel method for beam combination of two continuous wave pump beams. Due to stimulated Raman scattering, the RFL generates a Stokes beam which can be up to 300% brighter than the pump beams. Up to 5.8 W of Stokes power is generated with an optical conversion efficiency of 56%. For MM GRIN fibers, since there is no definite core and clad, in order to deduce the BE limitation, one needs to account for the ratio of the total pump modes area to the total first Stokes modes area. We will see below, that the BE potential is similar to that of Raman clad pumped lasers. 4. Graded index (GRIN) fiber (Multi-mode fiber) Thus we have demonstrated for the first time high-power (27 W) 2 nd-order random lasing at 996 nm in the all-fiber scheme of directly LD-pumped (at 915 nm) multimode graded-index fiber Raman It is attractive to use standard graded-index multimode passive fibers of all-fiber LD-pumped CW Raman laser based on the graded-index fiber. In the scheme of Raman fiber laser with direct diode pumping of a high power Numerical modeling and optimization of cladding-pumped tapered fiber Raman amplifiers. Direct Diode Pumped Raman Amplifier Based on a Multimode Graded Index Fiber. C Baird. 609 and Perception. References. Author Index. Subject Index. In this paper, continuous-wave Raman fiber amplifier based on multi-mode graded-index passive fiber with record 2.087 kW output power at 1130 nm is proposed with the optical-to-optical efficiency CW Raman fiber laser emitting at 954 nm under direct pumping a high-power multimode laser diode at 915 nm is demonstrated. A cavity of the laser is formed with 2.5 km-long multimode graded-index fiber and two mirrors: highly reflective fiber Bragg grating (FBG) at one side and normally cleaved fiber end at the other side. A low noise optical fiber Raman amplifier with integral Raman laser (FRA) is disclosed. The FRA typically comprises a fiber ring with at least two amplifier stages, with strictly counter-propagating pump radiation. Relatively short wavelength (e.g., 1060 nm) pump power is provided to the Raman laser portion of the fiber INDEX FIBER.

Nearly singlemode operation (LP 01) or (LP 11) mode of Raman fiber laser is demonstrated. Spectral filtration based on FBGs inscribed in a twin-core fiber in RDFB laser is shown. Also disclosed is the short cavity tunable laser coupled to a fiber amplifier.
