ABSTRACT:
A harmonics generation element which comprises a nonlinear optical element having single-crystals of lithium niobate containing magnesium of less than 5 atomic per cent. The nonlinear optical element has 3 ppm or less of impurity Fe and is configured so that a primary laser beam is made incident into the nonlinear optical element and a secondary output light having a wavelength of higher-order harmonics is emitted therefrom.
