Abstract
A second harmonic generation element including a single crystal substrate having a fundamental composition of K.sub.3 Li.sub.2-2x (Nb.sub.1-y Ta.sub.y).sub.5+5z O.sub.15-x+12.5z and an optical waveguide made of an epitaxial film with a fundamental composition of K.sub.3 Li.sub.2-2a (Nb.sub.1-b Ta.sub.b).sub.5+5c O.sub.15-a+12.5c and refractive index different from that of the single crystal substrate, wherein: EQU -0.5.ltoreq.a, x.ltoreq.0.625 EQU 0.ltoreq.b, y.ltoreq.0.5 EQU 0.8.ltoreq.(5-2x)/(5+5z), (5-2a)/(5+5c).ltoreq.1.2.
