Efficient Nd:Y0.36Gd0.64VO4-GdCa4O(BO3)3 red laser under diode pumping into the emitting level

Abstract  
We report a red laser at 671 nm generation by intracavity frequency doubling of a continuous wave (cw) laser operation of
a 1342 nm Nd:Y0.36Gd0.64VO4 laser under diode pumping into the emitting level 4
F
3/2. 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 17.8 W, as high as 1.12 W of cw output power at 671 nm is achieved. The optical-to-optical
conversion efficiency is up to 6.3%, and the fluctuation of the red output power was better than 3.5% in the given 30 min.
