| Abstract: | 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. |

| Keywords: | interference correlation equality-width measurement of pulse width |
