Abstract :
An efficient pump mechanism is required for the chromium-doped crystals and glasses for laser and amplifier applications. In this paper, Yb/sup 3+/ ion of which strong maximum-absorption is at around 980 nm, is introduced as a sensitizer of Cr/sup 4+/ ion in calcium-aluminate glasses in order to provide a suitable pump band.
