INTEGRATED QUASI-PHASE-MATCHED 2ND-HARMONIC GENERATOR AND ELECTROOPTIC SCANNER ON LITAO3 SINGLE-CRYSTALS

We report the first integrated quasi-phase-matched second-harmonic gen erator and electrooptic scanner on ferroelectric Z-cut LiTaO3. The qua si-phase-matched second-harmonic generation device frequency doubles t he infrared light at 829.7 mn into blue at 414.85 nm with a bulk cover sion efficiency of 0.52%/W-cm. The blue light generated in the bulk th en passes through an electrooptic scanner, consisting of a series of l ithographically defined triangular-shaped domain-inverted regions exte nding through the thickness of the crystal, A deflection of 12 mrad/kv for the output blue light and 7.4 mrad/kv for the infrared light was observed at the scanner output.
