Nd 3+ -doped Bi 2 O 3 -B 2 O 3 -TeO 2 glass for solar pumped lasers

We have studied Nd 3+ -doped Bi 2 O 3 -B 2 O 3 -TeO 2 glasses for solar pumped lasers, and compared with silicate glasses and YAG ceramics. Bi 2 O 3 -B 2 O 3 -TeO 2 glasses show broad band and large absorption compared to YAG ceramics, and longer fluorescence lifetime.
