Abstract

Aligning a pulsed CO₂ laser fusion system involves control systems which insure that the centers of beams follow a prescribed path to within 1 mm, that the pointing of the beams is correct to ~ 20 microradians, and that focal spot at the location of the experimental fusion target be placed to accuracies of 10-20 micrometers laterally and ~ 50 micrometers axially. These alignments are accomplished by a variety of sensing techniques which include thermal pinholes and quadrant detectors, Seebeck effect silicon detectors, and imaging autocollimating Hartmann test procedures employing it vidicon systems.
