Highly efficient continuous-wave operation at 1030 and 1075 nm wavelengths of LD-pumped Yb~(3+):Y_(2)O_(3) ceramic lasers

摘要

Room-temperature cw laser oscillations at 1030 and 1075 nm wavelengths were demonstrated for the TEM_(00) mode with Yb~(3+):Y_(2)O_(3) ceramics by LD-pumping. A maximum extraction efficiency of 72% at 1075 nm lasing wavelengths and of 45% at 1030 nm lasing wavelengths were observed.
