Abstract

In this paper, we report the first succesful integration of a solid state blue laser and an electro-optic scanner on the same LiTaO₃ wafer. Figure 1 shows the schematic of the integrated device. The first half (7.8 mm in length) of the device is a quasi-phase-matched second-harmonic generation device. It consists of a periodic domain inverted grating (Λ= 3.5 µm), phase-matching at λ= 2.Λ.[n_e^2ω- n_e^ω]= 829.7 nm, where n_e is the extraordinary refractive index. An infrared beam (polarization along c axis) is focussed at the center of the SHG grating in the bulk of the crystal, with a microscope objective of~0.01 N. A.
