摘要：

We report on a wavelength-tunable optical parametric amplifier (OPA) from 2.7 to 3.8 mu m seeded with carrier-envelope phase (CEP) stabilized pulses generated by intra-pulse difference frequency generation (DFG) using a commercial Yb:KGW chirped-pulse amplifier. The Yb:KGW laser's output pulses are spectrally broadened in two-stage multi-plate pulse compression from 0.8 to 1.25 mu m, which are compressed down to a sub-two-cycle duration of 6.5 fs using chirp mirrors. CEP-stabilized mid-infrared pulses are produced in intra-pulse DFG of the spectrally broaden pulses around 1.03 mu m and parametrically amplified in KTiOAsO4 crystals. The output energy and temporal duration of the OPA output pulses range from 31 to 56 mu J and from 102 to 203 fs, respectively. The root mean square value of their CEP errors is measured to be 101 mrad. (C) 2019 Optical Society of America under the terms of the OSA Open Access Publishing Agreement
