| Abstract: | We report the efficient generation of high-power laser radiation at 1053 and 1083 nm wavelength by using of a hybrid master oscillator fiber power amplifier system, consisting of a diode-pumped Yb-doped oxyorthosilicate solid state laser as the master oscillator and an Yb-doped large-mode-area fiber as the power amplifier. Efficient tunable diode-pumped Yb-doped oxyorthosilicate lasers at 1053 and 1083 nm have been constructed, which was scaled up to a maximum output power of 34.5 W at 1053 nm and 30.2 W at 1083 nm by a fiber power amplifier, corresponding to a slope efficiency of 93.9 and 87.8%, respectively. |
