Periodically poled titanium-diffusion waveguide was fabricated in near-stoichiometric MgO:LiNbO3 wafers. The characteristics of the device were examined by pump-probe second harmonic generation (SHG). The device shows very high resistance to photorefractive damage at room temperature. The wavelength tuning of the converted difference frequency (DF) wave can be achieved from 1450 to 1542 nm by tuning pump wave and signal wave. The wavelength conversion efficiency was measured to be -7.3 dB with coupled pump and signal power are 150 mW and 50 mW, respectively.
