Research abstract
Diode-pumped alkali laser systems (DPALS) are under development for high-energy airborne laser defense systems due to their extremely high theoretical optical efficiency, efficient thermal management, and comparatively small footprint. However, traditional antireflection coatings for the optics used in the alkali vapor cell of the laser cavity are rapidly destroyed by the harsh chemical environment, creating large optical losses and severely limiting the observed efficiencies. TDA is proposing the only class of binary materials that can provide high performance optical coatings while indefinitely surviving both the extremely reactive chemical environment and the intense radiation of the operating laser.
