Few-cycle short-wave-infrared light source for strong-field experiments at 200 kHz repetition rate
We present a compact, few-cycle, short-wave infrared light source delivering 13 μJ, carrier-envelope phase (CEP) stable pulses around 2 μm, operating at 200 kHz repetition rate. Starting from an ytterbium fiber amplifier, the seed is produced via white-light generation followed by difference frequency generation, and later amplified in two BiBO nonlinear crystals. A pulse duration of 15.8 fs is me
