A short-pulse high reflector EP mirror (SPHR10)

A view through a window in the Optical Manufacturing Group’s 72-in. coater shows an optic (SPHR10) in the upper left with plasma and evaporation sources below. Dual-plasma sources are used to provide stress control for optical coatings used in vacuum. The 0.8-m high-reflector mirror is the first production optic coated with the plasma-assist technology at LLE, and it will be used in the short-pulse transport section of OMEGA EP.
