Second harmonic waves generated in the form of Cherenkov radiation from a 0.8μm diode laser in proton-exchanged LiNbO3 waveguides have been observed. Low-loss and high-index waveguides were fabricated by using pyrophosphoric acid as a new proton source. Blue light of 1mW at 0.42μm was generated for a fundamental power of 65mW at 0.84μm at room temperature.
