Abstract

Recently, we have demonstrated multimillijoule optically synchronized and passively carrier-envelope-phase (CEP) stable optical parametric chirped-pulse amplification (OPCPA) at 1.5 µm [1]. Our four-stage infrared OPCPA system is based on a DPSS Yb-MOPA-driven (Pharos, Light Conversion Ltd.), CEP-stable front-end [2] and two successive power-amplification stages pumped by a 100-mJ 60-ps 20-Hz 1.064-µm Nd:YAG amplifier (Ekspla Ltd.), which is seeded from the Yb master oscillator [1]. In the amplification stages 2–4, we employ (nearly) collinear type-II phase matching in KTP/KTA reaching the pulse energy of ∼12.5 mJ at a 20-Hz repetition rate before a grating compressor.
