Efficient cw intracavity frequency doubling of a diode end-pumped Nd : Gd VO 4 laser that operates in the F 3 / 2 4 I 9 / 2 4 transition at 912 nm is demonstrated. A 15 mm long lithium borate crystal, cut for critical type I phase matching at room temperature, was used for second harmonic generation of the fundamental laser. A maximum output power of 14.8 W in the deep blue spectral range at 456 nm was achieved at an incident pump power of 40 W . In 2 h we achieved an optical-to-optical conversion efficiency of 37% with a better than 2.57% power stability.
