Abstract

Based on the dual-chirped optical parametric amplification and type-I BiB₃O₆(BiBO) crystals, the generation of >100 mJ, 10.4 fs, 10 Hz, carrier-to-envelope phase (CEP)-stable laser pulses, which are centered at 1.7 mm, was demonstrated; it produced a peak power of 10 TW. CEP-dependent high harmonic generation was implemented to confirm the sub-two-cycle pulse duration and CEP stabilization of infrared (IR) laser pulses. As far as we know, the obtained pulse energy and peak power represented the highest values for sub-two-cycle CEP-stable IR optical parametric amplification. Additionally, the prospects of achieving high-energy water window isolated attosecond pulses via our developed laser source were discussed.
