Abstract:

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.
