Supercontinuum-seeded, carrier-envelope,phase-stable, 4.5-W, 3.8- μ m, 6-cycle, KTA optical parametric amplifier driven by a 1.4-ps Yb:YAG thin-disk amplifier for nonperturbative spectroscopy in solids

We demonstrate a carrier-envelope phase (CEP)-stable, KTA (KTiOAsO_4)-based optical parametric amplifier (OPA) delivering 6-cycle (79   fs), 3.8- μ m pulses at a 100-kHz repetition rate with an average power of 4.5   W. The pivotal achievement is the stable generation of ...
