Generation of high power laser at 1314 nm from a diode-side-pumped Nd：YLF module

We demonstrate a high power continuous-wave(CW)and acoustic-optically(AO)Q-switched 1314-nm laser with a diode-side-pumped Nd:YLF module.A maximum CW output power of 21.6 W is obtained with a diode pump power of 180 W,corresponding to an optical-to-optical conversion efficiency of 12.0%and a slope efficiency of 16.1%.In the Q-switching operation,a highest pulse energy of 3.8 mJ is obtained at a pulse repetition rate of 1 kHz.The shortest pulse width and maximum single peak power are 101.9ns and 37.3 kW,respectively.
