Abstract

We report on the first observations, to our knowledge, of the   4 F 3 / 2   4 I 11 / 2 (1060-nm) induced fluorescence in a Nd-doped CaO Al 2 O 3 glass pumped by an 810-nm diode laser. This new doped glass is produced as a 3-mm-diameter sphere by heating and melting in an aerodynamic containerless trap and is rapidly solidified by radiative cooling ( > 350 K/s). This glass has an interesting Nd 3 + emission maximum at 1067 nm (not many doped glasses have their emission maxima close to 1067 nm). The measured fluorescence decay time of the   4 F 3 / 2 level is short (0.3 ms) when the ion is excited by a narrow-band pulsed dye laser.
