Abstract:
We have demonstrated a room-temperature laser on the (6)H(13/2) - (6)H(15/2) transition of Dy(3+) in Dy:BaYb(2)F(8) at 3.40 mum . A pulsed 1.3-microm Nd:YAG laser was used as the pump. Our measured spontaneous-emission spectrum for the (6)H(13/2) - (6)H(15/2) band indicates that this laser should be continuously tunable between 3.0 and 3.4 mum .
