Abstract
We present a novel coupling scheme of two independent amplified beam lines in a Nd:YAP based master oscillator power amplifier (MOPA) system. Second harmonic generation (SHG) with type II phase matching offers the possibility of coupling two perpendicularly polarized beams, which are delivered from a MOPA system with two parallel amplifier chains. To preserve the excellent oscillator beam quality after amplification, the amplifiers are driven in double pass and optical fibres as phase conjugate mirrors (PCM) are used after the first pass. With this method, a single beam with an average power of 124W is generated in the green spectral range. The laser system operates at an average repetition rate of 2.8kHz and delivers pulses with a width of 160ns.
