In this work, a promising solid-state laser material, Er-doped cadmium alum
inum silicate glass, has been synthesized by solid-state reaction. Very int
ense emission at 1534 nm, corresponding to the I-4(13/2)--> I-4(15/2) trans
ition of Er3+ ions, was observed upon both 488 nm Ar+ laser and 632.8 nm He
-Ne laser excitations at room temperature. Possible cross-relaxation proces
ses in the glass are discussed. (C) 2000 American Institute of Physics. [S0
