Abstract
Preparation of Sm2+-doped berate glasses for persistent spectral hole burni ng is studied experimentally. The influence of different metallic reducing agents on the reduction of Sm3+ to Sm2+ in berate glasses is discussed as w ell as the influence of phase separation in borosilicate glasses on the spe ctroscopic properties of Sm2+ ions. In Tb3+-doped silicate and berate glass es we demonstrate persistent spectral hole burning in the F-7(6)-D-5(4) exc itation line at temperatures below 50 K. The hole-burning properties and me chanism are discussed. (C) 2000 Elsevier Science B.V. All rights reserved.
