研究了以不等间距达曼(Dammann)型滤波器为模板的飞秒激光时空变换与识别技术。优化设计出不等间距多脉冲达曼型滤波器,并在高斯光谱分布的模拟中讨论产生的超快时域多脉冲平均度和光谱平面上调制周期重复数的相关性。给出了频率分辨光开关法(FROG)技术识别超快时域两脉冲的实验结果。
The space-time transform and recognition technology of femtosecond laser based on the Dammann-type filter is studied. In this paper, we optimize the design of unequal-spacing, multi-pulse Dahman filters and discuss the correlation between the ultrashort time-domain multi-pulse average and the repetition of the modulation period on the spectral plane in the simulation of Gaussian spectral distribution. The experimental results of FROG technique for identifying two pulses in ultrafast time domain are given.
