Abstract
A low diffraction-feedback high-energy laser system includes an injection laser, a master oscillator power amplifier (MOPA), and means for aligning the injection laser to the MOPA. The alignment means includes a relay mirror and sensor array cooperative to center the injection laser externally of the cavity, and the alignment means further includes a relay mirror and cooperative optics and sensor to center the injection laser interiorly of the cavity. The master oscillator power amplifier preferably includes a convex and a concave cavity. reflector. In one embodiment, an intracavity laser separator is disclosed for providing alignment of the injection laser, and in a further embodiment an extracavity laser separator is disclosed for providing injection laser alignment.
