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 2x10 16 to 8.3x10 20 n/cm 2 and greater. Further, the optical components have a bulk laser damage threshold of 105+/-20 J/cm 2 , a surface laser damage threshold of 72 +/- 15 J/cm 2 , a Stokes shift of about 9%, and a fractional thermal loading of about 11%. |
