Carrier-envelope phase-dependent high harmonic generation via loosely focused 10-TW sub-two-cycle pulses

By employing the dual-chirped optical parametric amplification and type-I BiBO crystals, an over 100 mJ, 10.4 fs, 10 Hz, carrier-to-envelope phase (CEP) stable laser pulses centered at 1.7 μm is achieved, which results in a peak power of 10 TW. In addition, the sub-two-cycle pulse duration and CEP stabilization are identified by the CEP-dependent high harmonic generation via a loosely focused geometry.
