Diode laser pumped blue-light source at 473 nm using intracavity frequency doubling of a 946 nm Nd:YAG laser

Using intracavity frequency doubling of a diode laser pumped 946 nm Nd laser, 3.1 mW of blue output power at 473 nm was obtained. Angle-tuned, type-I frequency doubling in potassium niobate was employed, and both the KNbO 3 and Nd crystals were used at room temperature.
