A thin film of a lithium niobate single crystal, formed on a lithium tantalate substrate, which is mainly used in a thin-film waveguide type of a second harmonic generating element which can halve the wavelength of an incident laser beam, is in a state of lattice matching with the lithium tantalate substrate, and exhibits a high electro-optical constant with a reduced propagation loss. |
