Abstract
Systems and methods for embodiments having an extra thick ultraviolet durability coating are described herein. For example, a system may include a laser block assembly. The system may also include a cavity in the laser block assembly. Further, the system may include a plurality of multilayer mirrors in the cavity. In certain embodiments, at least one multilayer mirror of the plurality of multilayer mirrors may include a plurality of alternating layers of a first optical material having a high index of refraction and a second optical material having a first low index of refraction. Additionally, the at least one multilayer mirror may include a multilayer durability coating disposed on the plurality of alternating layers.
