A three-stage high conversion efficiency optical parametric amplifier (OPA) with passively stabilized carrier-envelope phase (CEP) is presented. After passing through an argon-filled hollow fiber and the dispersion compensator for pulse compression, CEP stabilized 0.7 mJ, 1.5 cycle laser pulses at 1.75 μm center wavelength are obtained. Terahertz (THz) emission spectroscopy is adopted to determine the value of CEP, indicating an excellent long-term CEP stability.
本文介绍了一种具有被动稳定载波包络相位（CEP）的三级高转换效率光学参量放大器（OPA）。在经过充氩空心光纤和用于脉冲压缩的色散补偿器后，获得了中心波长为1.75μm、CEP稳定的0.7mJ、1.5周期激光脉冲。采用太赫兹（THz）发射光谱法确定CEP的值，表明其具有出色的长期CEP稳定性。
