摘要
近年来,高功率拉曼光纤激光器技术发展迅速,输出波长范围覆盖可见光至中红外波段,最大输出功率超过千瓦。在功率提升方面,拉曼光纤激光器技术的发展脉络可概括为:激光振荡器、主振功率放大器和抽运/信号集成放大器。在重要科研应用的驱动下,高功率窄线宽拉曼光纤放大器技术得到显著发展。另外,高功率拉曼光纤激光器技术还有一些新的扩展,包括包层抽运、二极管直接抽运以及拉曼光纤激光合束等,未来发展潜力巨大。
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.
