标题： High Power, Tunable, Continuous-Wave Fiber Lasers in the L-band using Cascaded Raman Amplifiers

摘要： 我们展示了一种高功率、全光纤、可调谐的激光源，可在L波段区域工作。 一种低功率、可调谐的输入激光通过一种最近提出的高效六阶级联拉曼放大器进行放大。 所提出的系统具有可扩展性，并克服了掺铒和掺铒-镱光纤激光器在功率扩展方面的限制。 一种可调谐的掺铒-镱光纤环形激光器，输出功率约为0.5W，在1560-1590 nm波长范围内可调，被用作种子光源。 使用六阶级联拉曼放大将种子激光的输出放大至约24 W。 一台在1117nm波长下工作的高功率镱激光器被用作驱动拉曼转换的泵浦激光器。 所演示激光器的工作波长处于人眼安全、大气透明的区域，使得其适用于高功率自由空间应用。 此外，该光源还能够实现其他有趣的应用，例如使用常规石英光纤进行高功率超连续谱生成。 显示英文摘要

摘要： We demonstrate a high power, all-fiber, tunable laser source that can operate in the L-band region. A low power, tunable input laser is amplified with a recently proposed, high efficiency, 6th order cascaded Raman amplifier. The proposed system is scalable and overcomes the limitations of Erbium and Erbium-Ytterbium co-doped fiber lasers for power scaling. A tunable Erbium-Ytterbium co-doped fiber ring laser generating ~0.5W of power and tunable in the 1560-1590 nm wavelength range is utilized as the seed source. The output from the seed laser is amplified to ~24 W using 6th order cascaded Raman amplification. A high power Yb laser operating at 1117nm is used as the pump laser for driving the Raman conversions. The operating wavelength of the demonstrated laser in the eye-safe, atmospherically transparent region enables high power free-space applications. In addition, this source enables other interesting applications such as high power supercontinuum generation with conventional silica fibers.
