Multiphonon relaxation of rare-earth ions in oxide glasses
TL;DR: In this paper, a series of oxide glasses were investigated for the nonradiative decay of excited rare-earth ions by multiphononon emission and the results showed that the strength of the ion-phonon coupling was approximately equal for all glasses.
Journal ArticleDOI
Laser-induced surface and coating damage
W. H. Lowdermilk,David Milam +1 more
TL;DR: In this paper, the results from experiments on laser-induced damage to surfaces of optically polished glass and fused-silica and thin-film coatings are presented, and data are given for distributions of thresholds for 1.06 μm, 1 ns pulses, the influence of coating materials and designs, and effects of surface preparation on damage threshold.
Journal ArticleDOI
Nonradiative relaxation of rare-earth ions in silicate laser glass
TL;DR: In this paper, the rates for nonradiative decay by multiphonon emission were measured for rare-earth ions in silicate laser glass and used to estimate quantum efficiencies.
