This paper presents the results of an analysis of the mechanism by which distortions are produced in laser mirrors by the thermal action of a coolant with a time-variable temperature. Methods are determined for reducing such distortions. A description is given of the thermally invariant design of a laser mirror that possesses enhanced stability against the thermal action of the coolant. A technique is described for comparative tests of mirrors with the thermally invariant design and the basic design, and the results are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
