我们提出了一种新型的具有被动稳定载波包络相位(CEP)的可调谐红外光学参数放大器(OPA)，其中使用了中空光纤来改善输出光束质量和克服空间啁啾问题。在800 nm泵浦光源的泵浦下，输出脉冲在1.2~2.4微米范围内可调谐，CEP稳定。最大输出平均能量约为(1.2W/40fs)/1 kHz，总抽运能量为(6.8W/40fs)/1 kHz。此外，还证明了由可调谐稳相OPA驱动的高次谐波产生。
We demonstrate what we believe to be a novel tunable IR optical parametric amplifier (OPA) with the passively stabilized carrier-envelope phase (CEP), in which a hollow fiber is used to improve the output beam quality and to overcome the spatial chirp issue. Pumped by an 800 nm pump source, the output pulses are tunable from 1.2 to 2.4 microm with the CEP stabilization. The maximum output average energy can reach approximately (1.2 W/40 fs)/1 kHz with the total of (6.8 W/40 fs)/1 kHz pump energy. Further, the high-order harmonic generation driven by the tunable phase-stabilized OPA has been demonstrated.
