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.
