ABSTRACT:
A coating consisting of polycrystalline Sm.sub.2 O.sub.3 powder dispersed in a Na.sub.2 SiO.sub.3 or K.sub.2 SiO.sub.3 binder may be provided on either the inner or outer lateral surface of a substantially tubular pumping cavity housing member for a Nd:YAG laser. The coating is absorptive of radiation at the lasing wavelength of about 1.06 .mu.m and has a thickness sufficient to provide a high diffuse reflectivity for pumping radiation.
