    Abstract

    By using quasi-phase matching technology, series of non-collinear harmonic pairs in more than five laser wave bands are realized in one piece of LiNbO3 nonlinear photonic crystal with two-dimensional dodecagonal superlattices when the laser wavelengths vary from 930 nm to 1307 nm. With the input fundamental wavelength decreasing from 1118.8 nm by nearly 52 nm, a pair of non-collinear green harmonics always exist except for one collinear harmonic for 1081.4 nm. More than three pairs of yellow harmonics appear on the screen at the input wavelength 1234.5 nm. The distance between pairs of red harmonics increases from 3.5 mm to 5.5 mm with input beam changing from 1306.1 nm to 1302.6 nm and the non-collinear harmonic spots look like triangles.
