| 摘 要： | 脉冲宽度40 fs,功率1.1 W的载波包络相位(CEP)稳定的飞秒激光脉冲在充氩气的空芯光纤内由于自相位调制频谱展宽,通过啁啾镜和斜劈补偿色散,最终可获得脉冲宽度为6 fs的载波包络相位稳定的强激光脉冲.将之应用到高次谐波实验中得到了脉冲宽度为500 as的单个阿秒脉冲.

| Abstract: | Carrier-envelope phase(CEP) stabilized 6 fs ultrashort intense pulses were generated by focusing(40 fs)(full width at half maximam(FWHM))(1.1 mJ)(pulse energy) intense laser pulses into the hollow fiber filled with argon gas.The input pulse was broadened by self-phase modulation and the spectrum was compressed by chirped mirrors and two titled quartz thin wedges.We applied the compressed pulse to the experiment of high-order harmonic generation and found it supporting a transform-limited 500 attosecond single pulse in time domain. |

| Keywords: | ultrashort optics 6 fs pulse frequency-domain broadening carrier-envelope phase locked high-order harmonic |
