By employing the dual-chirped optical parametric amplification (DC-OPA) method and type-I BiBO crystals, we demonstrate a 10 Hz, CEP stable, IR laser source with the output energy of over 100 mJ and pulse duration down to 10.4 fs (1.8-cycle at 1.7 um). In addition, the half-cycle cutoff (HCO) originated from a few-cycle pulse-driven HHG process has also been recorded
