A dual-wavelength continuous-wave (cw) diode-end-pumped Nd:YAlO3 (Nd:YAP) laser that generates simultaneous laser at the wavelengths 1079.5 nm and 1064.5 nm is demonstrated. The optimum oscillation condition for the simultaneous orthogonal polarized dual-wavelength operation has been derived. A polarization beam splitter was placed in the cavity to split the beams polarizing in two orthogonal directions. We obtained a total power output over 6.5 W in two orthogonal polarized beam directions with 4.64 W in c-axis polarization and 1.86 W in a-axis polarization. Intracavity sum-frequency mixing at 1079.5 and 1064.5 nm was then realized in a KTiOPO4 (KTP) crystal to reach the green range. We obtained a cw output power of 1.12 W at 536 nm at the incident pump power of 17.3 W.
