Abstract
Optical components that maintain transparency (remain clear) in high energy environments, including in applications of high-intensity gamma-ray radiation dosage of 1.29×109 rads and greater, and neutron energy at neutron fluxes ranging from 3×109 to 1×1014 n/cm2 sec and greater, and fluencies ranging from 2×1016 to 8.3×1020 n/cm2 and greater. Further, the optical components have a bulk laser damage threshold of 105+/−20 J/cm2, a surface laser damage threshold of 72+/−15 J/cm2, a Stokes shift of about 9%, and a fractional thermal loading of about 11%.
