Abstract
Persistent spectral hole burning is observed in Sm(2+)-doped glasses at room temperature. The holes are burned in the (7)F(0) ? (5)D(0), (5)D(1) lines of the Sm(2+) ions in three kinds of fluoride glass. The dependence of the burning efficiency on the sample and on the burning intensity is measured. The intensity dependence is approximately linear, and no antihole is observed around the burned hole. The hole-burning mechanism is discussed. The temperature dependence of the homogeneous width is also measured.Keywords
