Abstract
High-conversion-efficiency and tunable self-phase-stabilized infrared laser pulses have been generated from a two-stage optical parametric amplifier. With a 1 kHz repetition rate 800 nm pump source, the output idler pulses are tunable from 1.2 to 2.4 μm, and the maximum output average power of the idler pulses is >2 W with the total 7.4 W pump power, and the maximum parametric conversion efficiency in the final optical parametric amplifier is near 60%. Due to the differential frequency process, the output idler pulses is self-phase-stabilized, the phase fluctuation can reach 0.374 rad (rms).
