2022-09-23 2.79 μm laser performance of a 968 nm LD side-pumped Er:LuYSGG mixed crystal doi:10.57760/sciencedb.02814 en We demonstrate the laser performance of a 968 nm LD side-pumped Er:LuYSGG crystal rod by optimizing the cavity length and output coupler transmission. The maximum output power of 14.84 W is obtained at 150 A, 150 Hz, and 200 μs, corresponding to a slope efficiency of 17.2%. Under the high frequency of 500 Hz and short pulse width of 60 μs, an average output power of 7.27 W is achieved, corresponding to a slope efficiency of 7.1%. Additionally, the beam quality factors Mx2/My2 of 7.04/7.12 are also determined at 150 Hz and the average output power of 11.33 W. These results can provide valuable references for promoting the development of 2.7-3 μm lasers.
