Abstract

A novel interferometric method for the direct, real-time measurement of the complete temporal coherence function of a pulsed laser is presented. A Michelson interferometer is modified by replacing one mirror with an inclined diffraction grating to observe interference fringes as a function of path-length difference on a single pulse. Computerized data acquisition and methods of extending the range of wavelengths to the infrared are discussed.

摘要

提出了一种用于直接、实时测量脉冲激光完整时间相干函数的新型干涉测量方法。通过用倾斜衍射光栅取代迈克尔逊干涉仪中的一面镜子对其进行改进，从而在单个脉冲上观察干涉条纹随光程差的函数变化。讨论了计算机化数据采集以及将波长范围扩展到红外的方法。
