Frequency conversion of two laser diodes in a proton-exchanged MgO-doped LiNbO3 waveguide is reported. Simultaneous generation of blue (0.43 μm), green (0.52 μm), and red (0.65 μm) coherent radiation by sum-frequency and second-harmonic generation of laser diodes at wavelengths of 0.86 and 1.3 μm has been observed for the first time. This is made possible by the wide phase-matching bandwidth of the Cherenkov radiation scheme.
