Abstract

Stacking chirped pulse optical parametric amplification based on a home-built Yb3+-doped mode-locked fiber laser and an all-fiber pulse stacker has been demonstrated. Energic 11mJ shaped pulses with pulse duration of 2.3ns and a net total gain of higher than 1.1×107 at fluctuation less than 2% rms are achieved by optical parametric amplification pumped by a Q-switched Nd:YAG frequency-doubled laser, which provides a simple and efficient amplification scheme for temporally shaped pulses by stacking chirped pulse.
