    "abstract": "Phase-stabilized 12-fs, 1-nJ pulses from a commercial Ti:sapphire oscillator\nare directly amplified in a chirped-pulse optical parametric amplifier and\nrecompressed to yield near-transform-limited 17.3-fs pulses. The amplification\nprocess is demonstrated to be phase preserving and leads to 85-uJ,\ncarrier-envelope-offset phase-locked pulses at 1 kHz for 0.9 mJ of pump,\ncorresponding to a single-pass gain of 8.5 x 10^4.",
