This paper presents the results of a measurement of the critical energ
y of the thermal self-action and radiation stability of the magnetoopt
ic glasses MOS101, MOS105, MOS04, and MOS10. For comparison, the same
parameters are presented for K8 optical glass, KU-1 fused quartz, GLS-
22P laser phosphate glass, and TGG crystal. (C) 1997 The Optical Socie
