摘要：
A laser steering system based on the Ti-diffusion lithium niobate (LiNbO3) waveguides is presented. A phase shifter based on the LiNbO3 waveguide is designed. This waveguide can provide a continuous phase shift for laser-phased-array (LPA) by changing the voltage loaded on it. The theory of irregular LPA based on the Ti-diffusion LiNbO3 waveguide phase shifter is studied numerically and experimentally. Beam steering with an angle of 1.37 deg is gained by a 1 x 3 array setup that agrees well with the theory. (C) The Authors.
