研究了长周期光栅对双包层光纤放大器受激拉曼散射的抑制作用。用CO（2）激光器制作的LPG通过将来自有源芯的Stokes波长耦合到包层中来实现SRS抑制。在光纤脉冲放大器中只插入三个LPG，可提取的无拉曼输出功率几乎翻了一番。数值模拟的设置显示出良好的协议与实验结果。(C)2010年美国光学学会
We report on the suppression of stimulated Raman scattering (SRS) in a double-clad fiber amplifier using long-period gratings (LPGs). The LPGs, fabricated with a CO(2) laser, achieve SRS suppression by coupling the Stokes wavelength from the active core into the cladding. With only three LPGs inserted into a fiber pulse amplifier, the extractable Raman-free output power was nearly doubled. A numerical simulation of the setup shows good agreement with the experimental results. (C) 2010 Optical Society of America
