Abstract
A novel interferometric method for the direct, real-time measurement o f the complete temporal coherence function of a pulsed laser is presen ted. A Michelson interferometer is modified by replacing one mirror wi th an inclined diffraction grating to observe interference fringes as a function of path-length difference on a single pulse. Computerized d ata acquisition and methods of extending the range of wavelengths to t he infrared are discussed.
