A compact, blue light source using a GaAlAs laser diode and a guided-wave frequency doubler is demonstrated at room temperature. The 0.84pm wave from the laser diode is frequency doubled using the Cherenkov radiation scheme in a proton-exchanged LiNbO3waveguide. The conversion efficiency of the frequency doubler is 1.6%. Maximum harmonic output power of 1.05mW at 0.42pm was achieved for diode laser output power of 120mW, for a total conversion efficiency of 0.9%.
