Simple design of Yb-doped fiber laser with an output power of 2 kW

Ytterbium-Doped Fiber Laser as a Source of Coexisting Narrow-Band Thermal Light and Optical Rogue Waves: Experimental Demonstration

“…[1][2][3][4][5][6]. CW double-clad (DC) YDFLs are very efficient light sources with optical-tooptical conversion efficiency as high as 80% [1,7,8] and a wide optical range, from ~ 975 nm to ~ 1180 nm [9][10][11][12][13][14], with output power scalable up to very high levels, from several kW in single mode [7,8,15] to tens of kW in multi-mode configurations [16][17][18]. Due to very large power scaling and the perfect energy budget YDFLs found a great number of biomedical [19,20] and industrial applications [21], they can be used as an optical pump for other types of lasers [22][23][24][25], for frequency nonlinear conversion [26,27], and so on.…”
