... available at the output of an arm. Preliminary results from these experiments indicate that a significant reduction of the inclusion density can be obtained through changes in the vendor's glass melting conditions. platinum inclusions phosphate glass borosilicate glass large-area damage tests...

... Platinum inclusions in samples of laser glass were placed in the center of a 2-mm-diameter beam and repeatedly irradiated with 1064-nm laser pulses having durations of 1.3, 9 or 50 ns. The initial major dimensions of the particles ranged from 4–75 μm. The thresholds for initiation of damage were...

... at the pole exposed to laser light is larger than the lobe at the unexposed pole. A numerical heat-transport model predicts temperature profiles in and around a metallic platinum inclusion imbedded in a phosphate laser glass matrix when illuminated with 1-μm laser light. The thermal model predicts that glass...
