ABSTRACT:
A laser assembly and a novel glass laser disc having an annular lead borate glass coating for use in the assembly is disclosed, the annular coating being capable of absorbing energy at a wavelength of 1.06 microns to thereby absorb parasitic oscillations. The outstanding glass coating has an index of refraction not substantially less than the index of refraction of the glass disc, the glass coating containing an effective energy-absorbing amount of a heavy metal oxide, such as Sm.sub.2 O.sub.3 and CuO, for absorbing energy at a wavelength of about 1.06 microns. The heavy metal oxides includes oxides of transition metals of the 3d, 4d, 4f and 5f orbital series.
