Suppression of parasitic modes in a YAG:Nd slab laser using selective coating

摘要

The use of selective coating for suppression of parasitic modes in a slab laser with a YAG:Nd active element is investigated. Various designs of selective coatings are analyzed and optimized, based on the phenomenon of total internal reflection. The possibility of implementing a selective coating based on thin-film materials titanium, silicon dioxide, and aluminum oxide is demonstrated. (c) 2018 Optical Society of America
