Abstract
In this contribution we report on a 80 kHz repetition rate compact high power fiber amplifier pumped optical parametric chirped pulse amplifier (OPCPA) delivering 16.2 muJ pulses with a pulse duration of 50.7 fs. High repetition rate optical parametric amplifiers (OPAs) are typically driven by fiber chirped pulse amplification (FCPA) systems. Pulse energies of up to 81muJ and pulse peak powers up to 2 GW have been generated by an OPA, which was driven by a mJ-FCPA system, incorporating a quite large stretcher compressor system (stretched pulse duration 2 ns). The approach presented here generates high energy pump pulses through direct amplification in a large mode area photonic crystal fiber without the need of a FCPA system and is therefore less complex and more compact.
