Abstract
The Petawatt Field Synthesizer (PFS) is an OPCPA driven light source that is currently being developed at the Max-Planck-Institut für Quantenoptik in Garching, Germany. The target parameters are few-cycle, waveform-controlled light pulses with a repetition rate of 10 Hz and a peak power in the Petawatt regime [1]. The system relies on a cascaded broadband OPCPA that is pumped by a picosecond, all-diode-pumped Yb:YAG chirped-pulse-amplification (CPA) laser chain, the PFS pumplaser. In its final version, the pumplaser has to deliver nanosecond pulses with energies above 10 J at a wavelength of 1030 nm that can be compressed down to 1 picosecond and converted to 515 nm. Here, we report on the design and current performance of the new 2 J amplifier and discuss the design and ongoing development of the final 10 J amplifier.
