A novel method of generating 1.634-[mu]m laser action from Er:YAG crystals pumped intracavity by an Er:glass laser emitting at 1.549 [mu]m is described. Operation of the Er:glass laser at 1.549 [mu]m (red shifted from the standard 1.532 [mu]m, but with comparable output) at 300 K was obtained using mirrors with tailored spectral reflectivities. Several Er:YAG crystals ranging in concentration from 0.3% to 2% and in length from 1 cm to 8 cm were lased in the intracavity pumping arrangement. All the Er:YAG crystals lased in the [sup 4]I[sub 13/2]:Y1(6,544 cm[sup [minus]1])-[sup 4]I[sub 15/2]:Z6(424 cm[sup [minus]1]) 1.634-[mu]m transition at 300 K.
