Abstract

Results are presented for generation of visible and mid-IR output using a common fibre-based laser pump source. This source comprised a master oscillator power amplifier (MOPA) configuration incorporating a semiconductor seed source. Operation in the nanosecond and picosecond range is possible via use of the appropriate seed source. The MOPA is capable of generating 100 W average power in an output beam with an M2 of 1.1. Here the MOPA was operated in the nanosecond regime, using 100 ns seed pulses at a pulse repetition frequency of 100 kHz. 40 W each of pump power was available for a frequency doubling and an OPO stage. 9.8 W of green light was generated in an output beam with an M2 of 1.2; using a degenerate PPLN OPO 12.7 W of broadband mid-IR output, with a FWHM linewidth in excess of 170 nm, was generated.
