利用光谱位相干涉直接重构光脉冲的方法 (SPIDER) ,对最近建成的 15TW 35fs台式掺钛蓝宝石超短超强激光系统的输出脉冲特性进行了测量。测量内容包括输出脉冲的相对位相分布和脉冲强度随时间的变化情况。结果显示 ,输出脉冲具有好的相对位相分布 (各光谱之间相对位相差 <2π) ,输出脉冲半高宽为 33fs,表明此系统的脉冲输出已经达到了设计的要求。 The output pulse characteristics of the recently completed 15TW 35fs Ti: sapphire ultra-short super laser system were measured by the method of spectral phase interference reconstruction (SPIDER). The measurement includes the relative phase distribution of the output pulse and the change of the pulse intensity with time. The results show that the output pulse has a good relative phase distribution (the relative difference between the spectra is less than 2π) and the full width at half maximum of the output pulse is 33fs, indicating that the pulse output of this system has reached the design requirements.
