Title: High power blue light generation by frequency doubling of a laser diode in a periodically domain-inverted LiTaO3 waveguide
Abstract: We report high power and stable blue-light generation by frequency doubling a laser diode, stabilized by a grating feedback technique, in a periodically domain-inverted LiTaO3 waveguide. Due to the deep domain-inverted regions and strong waveguide confinement formed by proton-exchange and a quick heat treatment, high efficiency second harmonic generation (SHG) has been obtained. Locking the oscillation wavelength of a laser diode through the waveguide by a grating feedback technique, 8 mW of stable blue SHG has been demonstrated.
