Abstract
The far field energy distribution of a 10.6 u laser beam can be altered by optical means to favorably match the field of view of an imaging system with a linear array of detectors. In this paper we describe a laser beam shaper which consists of an anamorphic optical system and a X/2 phase step which is introduced into the central part of the laser beam. It is shown that with proper design, most of the laser energy can be made to fall within the field of view of the linear array and with nearly equal distribution among the detectors.
