Abstract
The present invention relates to an optical functioning glass containing Nd.sup.+3 as an active ion which amplifies an input light, and at least one other optical active ion different from Nd.sup.+3 which absorbs light at and near 1 .mu.m. The present invention also relates to an optical functioning glass containing Nd.sup.+3 as an active ion which amplifies the input light, and at least one other optical active ion different from Nd.sup.+3 functioning as a promoter. An efficiency of the stimulated emission of Nd.sup.3+ caused by signal light propagated through the optical functioning glass is enhanced and a gain of the light amplification at 1.3 .mu.m is increased.
