Abstract

In laser applications, unwanted transmission can require a beam dump positioned behind every mirror to prevent unwanted light propagation. Novel new mirrors (patent pending) based on an engineered substrate are able to reduce the power leaking through a component by several orders of magnitude while maintaining <98% of the reflective properties. Rated as both mirrors and neutral density filters, these parts greatly reduce the need for beam dumps behind components, minimizing the size of optical systems and improving laser safety. This paper will discuss the performance of these engineered mirrors and compare their reflection and transmission with traditional Fused Silica mirrors.
