Optical components that maintain transparency (remain clear) in high energy environments, including in applications of high-intensity gamma-ray radiation dosage of 1.29 x 10 9 rads and greater, and neutron energy at neutron fluxes ranging from 3x10 9 to 1x10 14 n/cm2 sec and greater, and fluencies ranging from 2x1016 to 8.3x10 20 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%.
L'invention concerne des composants optiques qui conservent leur transparence (restent incolores) dans des environnements de haute énergie, y compris dans des applications de dosage de rayonnement de rayons gamma de forte intensité de 1,29 x 109 rads et plus, et d'énergie neutronique à des flux neutroniques allant de 3 x 109 à 1 x 1014 n/cm2 s et plus, et des fluidités allant de 2 x 1016 à 8,3 x 1020 n/cm2 et plus. En outre, les composants optiques ont un seuil de détérioration laser en volume de 105 +/- 20 J/cm2, un seuil de détérioration laser en surface de 72 +/- 15 J/cm2, un décalage de Stokes d'environ 9 %, et une charge thermique fractionnelle d'environ 11 %.
