ABSTRACT:
A novel optical alignment system and method is provided for detecting misalignment of the optical components of a high energy laser comprising a source of radiation, such as a HeNe laser, for providing an alignment beam to intersect the optical path of the high energy system, optical beam splitting means at the intersection of the alignment beam and optical path to direct a first portion of the alignment beam toward the target and a second portion to the high energy cavity, the second portion interacting with the high energy cavity to provide a return beam along the alignment beam axis, and means to display and view the return beam relative to the alignment beam axis.
