Abstract

Identification of single reflection and multiple reflection ghosts in high energy laser systems is essential for the safeguard of components, equipment, and personnel. Most ray trace programs require the user to model each path of reflections as an independent optical system. We will describe some of our work on cw and pulsed laser systems with OPTICAD, a program which permits simultaneous display of all ghost paths. We will describe some of its features, such as limiting the search for ghost paths to those which have less than a user specified fraction of the input power.
