High-Repetition Rate, CEP-stable Shortwave Infrared Source with Two-Cycle Pulses for Field-Resolved Spectroscopy
<p dir="ltr">We report on a passively carrier-envelope phase (CEP) stable optical parametric amplifier generating two-cycle pulses at 2060 nm with energies of up to 2.25 μJ operating at a repetition rate of 400 kHz, specifically designed for applications in field-resolved spectroscopy. The measured pulse duration is 13.6 fs, resulting in 2 cycles of the carrier wave. Due to the robust CEP-stable front-end design, we achieve exceptional open-loop CEP stability of 250 mrad (rms) and the capability for fast CEP modulation.</p>
