Paper Abstract

We have demonstrated stable operation of a 2-kW Yb:YAG phase-conjugate master oscillator, power amplifier (PC-MOPA) laser system with a loop phase-conjugate mirror (LPCM). This is the first demonstration of a CW-input LPCM MOPA operating at a power greater than 1 kW with a nearly diffraction-limited output beam. The single-pass beam quality incident on the LPCM varied with the specific operating conditions, but it was typically ~ 20 times diffraction-limited (XDL). The measured beam quality with a MOPA output power of 1.65 kW was 1.3 XDL.
