摘要：

We have carried out a detailed spectroscopic characterization of Nd:GdVO4, a new laser crystal with high effective absorption and emission cross sections. The accidental degeneracy of the upper F-4(3/2) laser level decreases the number of emission lines and creates - together with the anisotropic crystal field - high emission cross sections (7.6 x 10(-19) cm2 at 1.06 mum and 300 K). In addition, the lines are strongly homogeneously broadened (1.6 nm for the 808.4 nm diode-laser pump transition). The temperature dependences of lifetime, linewidths, and cross sections have been determined. Slope efficiencies up to 57% with respect to the absorbed diode-laser pump power and output powers up to 0.8 W have been achieved at 1.06 mum from a 2 mm long crystal. Intracavity second-harmonic generation, using a KTP crystal, is demonstrated.
