Dual-wavelength Nd:YVO laser with two-crystal geometry

Dual-wavelength operation of a Nd:YVO laser based on two-crystal geometry with the a- and c-cuts was demonstrated. The laser delivered continuous-wave radiation at 1064.4 nm and 1066.6 nm with more than 450 mW of output power. Optical-to-optical efficiency reached more than 50%. The proposed design is suitable for diode-pumping and can lead to compact and efficient dual-wavelength lasers.
