Alignment system for lasers
Patent
·
OSTI ID:6339617
The system to be aligned includes a concave spherical reflector confocal with a convex mirror which is mounted together with a scraper mirror on a common support. The concave mirror is pivotally mounted for tilting about axes extending transversely to the optical axis of the cavity and it includes a spherical extension. The scraper mirror and the convex mirror are mounted for common tilting about axes extending tranversely to the direction into which the laser beam is directed by the scraper mirror. Two autocollimation systems include a collimating flat on the support as well as a diverging-recollimating system thereon, the latter being optically aligned with the spherical mirror extension; both systems monitor misalignment of the axes of the mirrors, and cause corrective tilting, whereby specifically translational and rotational misalignment of the concave mirror is corrected by tilting.
