Dual-wavelength Nd:YVO laser with c-cut crystal geometry

Dual-wavelength operation of a c-cut Nd:YVO laser at 1062.7/1066.6 nm was demonstrated by using a birefringent filter. The laser was pumped by a home-built Ti:sapphire laser operating at 808 nm. The maximum continuous-wave output power of 300 mW for 800 mW of pump power was obtained. This corresponded to 39% of optical-to-optical efficiency. The proposed design is also suitable for diode-pumping.
