Tunable phase-stabilized infrared parametric laser source

This paper reports that the tunable self-phase-stabilized infraredlaser pulses have been generated from a two-stage optical parametricamplifier. With an 800,nm pump source, the output idler pulses aretunable from 1.3,$mu $m to 2.3,$mu $m, and the maximum outputenergy of the idler pulses is higher than 1,mJ at 1.6,$mu $m byusing 6,mJ pump laser. A carrier-envelope phase fluctuation of$sim $0.15,rad (rms) for the idler pulses is measured for longerthan one hour by using a home build f-to-2f interferometer.
