通过三级钛宝石泵浦的BiB3O6晶体中钛宝石泵浦的光参量啁啾脉冲放大器，获得了3 mJ、两个周期(11.4 fs)、1 kHz、载波包络相位(CEP)稳定的1.7微米激光输出。我们在最后一级实现了18%的泵浦-信号转换效率，据我们所知，这是目前为止实现的近倍频程带宽放大的最高效率。F-to-2f测量表明，CEP在1h内的不稳定性为165mrad。这是在软X射线区产生孤立阿秒脉冲的理想光源。(C)2016年度美国光学学会
We produce a 3 mJ, two-cycle (11.4 fs), 1 kHz, carrier-envelope phase (CEP)-stable laser source at 1.7 mu m via a three-stage Ti:sapphire-pumped optical parametric chirped-pulse amplifier in BiB3O6. We achieve a pump-to-signal conversion efficiency of 18% in the last stage, which is, to the best of our knowledge, the highest yet achieved for near-octave bandwidth amplification. A f-to-2f measurement shows a CEP instability of 165 mrad over 1 h. This is an ideal light source for generating isolated attosecond pulses in the soft x-ray region.
