In recent years, high power Raman fiber lasers have progressed significantly. The output wavelength covers from visible to mid-infrared. The maximum output power can be higher than a thousand watts. For power scaling, the Raman fiber lasers have utilized schemes of laser oscillator, master oscillator power amplifier, and pump and signal integrated amplifier. Motivated by important scientific applications, high power narrow linewidth Raman fiber amplifiers have advanced greatly as well. Moreover, new Raman fiber laser schemes are emerging, for example, cladding pumping, laser diode direct pumping, and Raman fiber laser beam combining etc. There is a great potential for Raman fiber laser technology in the future.
