我们提出了一种实验技术，能够单次拍摄记录的超短激光脉冲声图通过使用双光子吸收在传统的硅CCD相机。二次光谱相位，引入到一个100飞秒脉冲的光栅展宽器，进行了测量，发现与解析计算值吻合得很好。硅的非线性响应允许在从1到2 μ m的波长范围内的声谱图表征。
We present an experimental technique capable of single-shot recording of an ultrashort laser pulse sonogram by use of two-photon absorption in a conventional silicon CCD camera. The quadratic spectral phase, introduced into a 100-fs pulse by a grating stretcher, was measured and found to be in good agreement with the analytically calculated value. The nonlinear response of silicon allows sonogram characterization in a wavelength range from 1 to 2 mum .
