Degenerated optical parametric chirped-pulse amplification using periodically poled LiTaO{sub}3

摘要

A high-gain preamplifier centered at 1064nm based on optical parametric chirped pulse amplification was demonstrated using periodically poled LiTaO{sub}3. The gain of ～10{sup}6 and ～10.3% conversion efficiency were achieved with low pump energy.
