Thermal optical software (THROP1) has been wriUen and used to reduce surface temperature and optical transmission thermal distortion interferometry data. A high reflectance mirror on a fused silica substrate was irradiated by a high intensity laser 1eam at 1.3 im. Surface temperature and optical transmission data that anchor the software are presented in this paper. In addition, a novel method of computing the optical transfer function from the interferometer data is discussed.
By properly designing the laser optical resonator, an optimal match between brightness and coherence can be achieved. This paper discusses one such design for an oxygen iodine laser and shows measured beam profiles. The laser mode was shaped and optically relayed to a test specimen. Very uniform beams of high brightness were measured at the plane of the test sample. This paper also presents this data.
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.
