We have achieved cw second-harmonic generation using an intracavity Ba2NaNb5O15 doubler crystal in a low-power NdP5O14 laser pumped by a dye laser. Our results show the feasibility of obtaining visible (0.525 μm) second-harmonic radiation from similar lasers pumped by near-infrared semiconductor sources.
