Abstract
A device for converting the frequency of coherent light from a prescribed wavelength range characterized by utilizing at least one crystal consisting of a nonlinear optical material. In order to obtain phase adjustment or phase matching, the device of the present invention provides a crystal possessing a property, which, at least for a specific wavelength of .lambda..sub.u from a wavelength range, the phase adjustment angle .theta..sub.0 and the phase adjustment temperature of T.sub.0 do not depend upon the wavelength at least in the first approximation. Thus, known methods of phase adjustments such as continuously rotating the crystal and/or changing the temperature are not required to adjust the phase when the frequency of the wavelength is changed within certain limits.
