Theoretical study of Raman fiber laser and random fiber laser

We present results on Raman fiber laser and random fiber laser. We theoretically analyzed the optical conversion efficiency in core and cladding pumped Raman fiber lasers. For cladding pumped Raman fiber laser, we change the cladding area and core area ration, fiber length, reflectivity of output FBG, Raman gain for improving the laser efficiency. At last we present a study of power output characteristics of random fiber lasers based on the half-open cavity by one or two fiber Bragg gratings, through our theoretical study we can know how to change the laser structure or fiber parameters to obtain the laser power and laser wavelength we want.
