Abstract

This paper reports that the tunable self-phase-stabilized infrared laser pulses have been generated from a two-stage optical parametric amplifier. With an 800 nm pump source, the output idler pulses are tunable from 1.3μm to 2.3μm, and the maximum output energy of the idler pulses is higher than 1 mJ at 1.6μm by using 6 mJ pump laser. A carrier-envelope phase fluctuation of ∼0.15 rad (rms) for the idler pulses is measured for longer than one hour by using a home build f-to-2f interferometer.
