The following results have been obtained.1. Theory of intensity correlation of an envelope of light pulse.We have made the theory of the pulse envelope measurement with intensity interference method using a Michelson interferrometer. In this measurement the envelope correlation can be measured together with the ordinary phase coherence time. The time resolution can be as fast as the optical period, and the wavelength can go to the ultraviolet.2. Measurement of a laser pulse width.We have succeeded in the measurement of a picosecond laser pulse width like with the common second harmonic autocorrelation measurement.3. Two-photon correlation measurement of squeezed pulses.We have succeeded in a measurement of the statistical distribrution of squeezed pulses generated from a parametric amplifier.

得到如下结果： 1．光脉冲包络强度相关理论。我们提出了利用迈克尔逊干涉仪用强度干涉法测量脉冲包络的理论。在该测量中，包络相关性可以与普通相位相干时间一起测量。时间分辨率可达到光周期，波长可达到紫外光。 2．激光脉冲宽度的测量。与常见的二次谐波自相关测量一样，我们成功地实现了皮秒激光脉冲宽度的测量。 3．压缩脉冲的双光子相关测量。我们成功地测量了参量放大器生成的压缩脉冲的统计分布。
