Growth, spectral properties, and laser demonstration of Yb3+: BaGd2(MoO4)(4) cleavage crystal

摘要

Detailed polarized spectral properties of a 3.6 at. Yb3+:BaGd2(MoO4)(4) (Yb3+:BGM) cleavage crystal grown by the Czochralski method have been investigated, including the absorption cross section, the emission cross-section, and the fluorescence lifetime. The evaluation of the laser potentiality shows that the Yb3+:BGM crystal is promising for tunable and ultrashort laser generations around 1 mu m. The room temperature quasi-CW laser operation of an unprocessed 3.6 at. Yb3+:BGM cleavage plate has been demonstrated with diode pumping. The results indicate that the Yb3+:BGM crystal is a good candidate for microchip laser gain medium by cleavage technique. (c) 2007 American Institute of Physics.
