摘要：

An all-fiber dad pumped Raman fiber laser (FL) oscillator with a CW power of 1.2 kW and an efficiency of 85% is presented. To the best of our knowledge, this laser is the highest power and the highest efficiency Raman FL demonstrated in any configuration with brightness enhancement (BE). To the best of our knowledge, it is also the first greater than kilowatt FL of any kind that does not utilize rare-earth doping in the oscillator fiber (all passive fiber). The beam quality (BQ) of the Raman laser was M-2 = 2.75 at 1 kW, and the pump-Stokes BE factor was approximately 7. The laser consists of a specially designed triple-clad fiber which confines the low BQ pump power into the multi-mode inner clad, while generating the Raman signal in the large-mode-area core. The second Stokes is inhibited by selecting the appropriate inner clad-to-core area ratio and by the oscillator's selective fiber Bragg grating reflectors. (C) 2018 Optical Society of America
