Abstract

A compact dual wavelength Nd:YVO₄/MgO:PPLN infrared laser was developed successfully which was composed of Nd:YVO₄ crystal, MgO:PPLN crystal and a cavity mirror(M1). The fundamental laser was consisted of the first face of Nd:YVO₄ and M1, and the optical parametric oscillation(OPO) cavity defined by the second face of Nd:YVO₄ and M1. The infrared laser output with wavelengths of 1539 nm and 3447 nm was obtained using intracavity cw OPO technology. The output power of 1539nm and 3447nm were 670mW and 236mW at the pumped LD power of 6.0 W, and the optical conversion efficiency was 15.1%. The higher conversion efficiency was mainly attributed the 2mm thickness of MgO:PPLN crystal. Intracavity dual wavelength laser can be used in spectrum detection, drunk driving test and so on.
