摘要
就高斯形、指数形、双曲正割形、罗伦兹形及衍射函数形脉冲的二阶强度相关函数和干涉相关函数进行了计算,并找出了前者半宽度与后者上包络宽度“等值”的位置,从而为采用干涉相关法测量超短脉冲宽度提供理论依据。
This paper deals with the calculations of the second order intensity correlation and interference correlation functions of the opticai pulses of Gaussian, exponential, hyperbolic secant, Lorentzian and diffractive shapes. The positions of the equality-width of the up-envelope of the latter are found. The equality-width is equivalent to the former's FWHM. It provides the theoretical basis for interference correlation measurement.
