Abstract:
We report on a Kerr-lens mode-locked Yb:YAlO3 laser gen-erating soliton pulses as short as 24 fs at 1085 nm with an average output power of 186 mW and a pulse repeti-tion rate of 87.5 MHz, representing the shortest pulses ever achieved from any mode-locked laser based on Yb3+-doped structurally ordered crystal. Optimized for power-scalable operation, the Yb:YAlO3 laser delivers 1.9 W at 1060 nm at the expense of a longer pulse duration of 44 fs, correspond-ing to a peak power of 462 kW and an optical efficiency of 43.2%.(c) 2022 Optica Publishing Group
