Investigation of the high-temporal contrast seed pulse amplification in optical parametric chirped pulse amplifier

摘要

We theoretically and experimentally investigate the amplification of a high-temporal contrast seed pulse in an optical parametric chirped pulse amplifier. The amplified and compressed signal pulse contrast can be improved by using large seed pulse energies. And the theory model is modified for considering the seed pulse contrast and compressed pulse duration. From the modified model the calculated results agree with the experimental results better.
