Cryogenic Yb:YGAG ceramic laser pumped at 940 nm and zero-phonon-line: a comparative study
Original language description
We present a comparative study on a continuous-wave laser operation of Yb-doped Y3Ga2Al3O12 (Yb:YGAG) ceramic at cryogenic temperatures with conventional pumping (940 nm) and zero phonon line pumping (969 nm) under identical experimental conditions. In CW laser operation, at 80 K with ZPL pumping, a maximum output power of 6.53 W with a slope efficiency of 52.0% is achieved with respect to incident power. When compared between two pump sources at cryogenic temperatures, ZPL pumping performs better due to the difference of quantum defect between the two pump sources that results in different heat load in the sample. In passive Q-switching experiment, at 100 K, with 85% initial transmission of Cr:YAG, an average output power of 3.37 W with a repetition rate of 17.6 kHz was achieved.n
