摘要
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15 TW/35 fs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33 fs,表明此系统的脉冲输出已经达到了设计的要求。
Abstract
By means of the method of SPIDER (Spectral Phase Interferometry for Direct Electrical Reconstruction) , the characteristics of the output of a 15 TW/35 fs table top Ti∶sapphire ultrashort ultraintense laser system have been measured, which include the phase and the time depended intensity of the pulse. The results show that the output pulse of this system has good relative phase distribution )the phase difference between every two spectrums<2π), and the duration of the output pulse is 33fs. Consequently, the system has reached the aim of the design.
