WebJun 1, 2001 · In a practical high-power Raman fiber laser, the output from a 35-W, fiber-coupled semiconductor-laser bar is used to pump the cladding of a double-clad ytterbium (Yb) fiber laser (see Fig. 1). The light from the Yb fiber laser then enters a cascaded Raman resonator, which has FBG end mirrors. WebAbstract. High-power continuous-wave single-frequency Er-doped fiber amplifiers at 1560 nm by in-band and core pumping of a 1480 nm Raman fiber laser are investigated in detail. Both co- and counter-pumping configurations are studied experimentally. Up to 59.1 W output and 90% efficiency were obtained in the fundamental mode and linear ...
