Abstract

The present paper reports a simple method for measurement of temporal coherence of a laser using holographically generated phase conjugate wavefront employing an iron doped LiNbO3 (0 . 1 ) crystal . In this method one has to see only the presence of a laser point on the screen rather than to observe interference fringes as in Michelson method. 1 .
