Abstract
A laser or other light beam is directed onto an optical substrate while an optical coating is being vacuum deposited thereon. The laser has a wavelength at or near that at which a reduced absorptance of the coating is desired. In one embodiment, the substrate is heated electrically. Thin film optical coatings having a substantially lowered absorptance are made in this manner.
