Study of optical parametric chirped pulse amplification at 1064 and 780 nm

Abstract

We investigated high gain optical parametric chirped pulse amplifications at 1064 and 780 nm by using LBO crystals and periodically poled LiTa03 (PPLT), pumped by synchronized frequency-doubled Nd:glass laser, Ti: sapphire laser, and Nd:YAG laser. Gain of 6 × 1010 at 1064 nm with three-stage amplifiers, single pass gain of 3.7 × 106 at 780 nm using LBO, and single pass gain of 1.7 × 106 at 1064 nm in a PPLT have been demonstrated. © 2007 Springer-Verlag New York.
