Continous wave diode pumped Nd:GdVO₄ groud state laser and intracavity frequency doubling to 456 nm. — •M. Schmidt, C. Czeranowsky, E. Heumann, and G. Huber — Institut für Laser - Physik, Universität Hamburg, Jungiusstr. 9a, 20355 Hamburg

We present to our knowledge for the first time a cw - diode pumped Nd:GdVO₄ laser on the ⁴F_3/2 - ⁴I_9/2 - ground state transition at 912nm. The maximum output power was 190 mW at 1.2 W input power with a slope efficiency of 24 %. Intracavity frequency doubling with LiB₃O₁₂ was shown with a maximum output power of 30 mW at 456 nm.

In addition the spectral data of the crystal will be presented with regard to the better well known and identical structured Nd:YVO₄.
