The gain curve in periodically poled LiTaO3 crystal (PPLT) was calculated for type 0 (e+e→e) quasi-phase matching (QPM). A high-gain amplifier centered at 1064nm based on degenerated optical parametric chirped-pulse amplification was built. The gain of 106 and 10.3% conversion efficiency were achieved with low pump energy of several hundreds of μJ. The experimental results are consistent with the simulation.
