We report the efficient compact red laser at 670 nm generation by intracavity frequency doubling of a continuous wave laser operation of a diode pumped Nd:GdVO4 laser on the (4) F (3/2) -> (4) I (13/2) transition at 1340 nm. An GdCa4O(BO3)(3) (GdCOB) crystal, cut for critical type I phase matching at room temperature is used for second harmonic generation of the laser. At an incident pump power of 18.2 W, as high as 1.32 W of continuous wave (CW) output power at 670 nm is achieved with 15-mm-long GdCOB. The optical-to-optical conversion efficiency is up to 7.3%, and the fluctuation of the red output power was better than 3.5% in the given 30 min.
