High energy chirped pulse characteristics observed by spectral-resolved streak camera
光谱分辨条纹相机测量高能啁啾脉冲特性

We observed the characteristics of high energy nanosecond chirped pulse by spectral-resolved streak camera,which works well with energetic chirped pulse of nanosecond pulse duration.At the same time,it can monitor the alignment of grating compressor.The measurement results show that the pulse generated by PW demonstration facility is linearly chirped,verifying the compressibility of amplified nanosecond pulse.
