Research abstract
Physical Sciences Inc. (PSI) proposes to develop a nanostructured, alkali vapor resistant, antireflective coating for use on Diode Pumped Alkali Laser (DPAL) windows. The materials will be deposited from chemical solutions via dip coating. A dual layer AR coating design is proposed including a dense alkali impervious base layer and a porous non-reactive top layer. The result of the Phase I effort will be the fabrication of both quartz and sapphire windows with>98% transmission at the rubidium D1 and D2 lines that are compatible with a rubidium number density of 1013/cm3, an operating temperature of 200oC, and a pump power of 10kW/cm2. The Phase I Option will examine the effect of other alkali materials on the AR coating. The Phase II effort will demonstrate the ability to integrate these windows into DPAL systems, scalability of the coating process, and cost-effectiveness of the proposed technology.
