【摘要】 现有的基于光谱相位相干电场重构法(SPIDER)的脉冲测量系统,在测量啁啾脉冲时容易出现误差.本文提出一个改进型零附加相位光谱相位相干电场重构系统(MZAP-SPIDER),来解决上述问题.在实验上,利用改进后的SPIDER系统测量了钛宝石飞秒激光器输出的脉冲及其经80mm长的BK7玻璃块展宽得到的啁啾脉冲.结果表明,该系统能胜任啁啾脉冲的相位测量.更多还原

【Abstract】 At present,pulse measurement systems based on spectral phase interferometry for direct electric-field reconstruction (SPIDER) may have problems in chirped pulse characterization. In this paper we propose and demostrate a Modified-ZAP SPIDER system to solve this problem. Femtosecond pulses from a KLM Ti:sapphire laser and the chirped pulses obtained by broadening by a 80 mm BK7 glass block are respectively measured. The experimental results show that the novel MZAP-SPIDER system performs well in chirped pulse measurement.更多还原
