The wavelength dispersion of the high-frequency quadratic electro-optic coefficient is important for designing of ultrahigh-speed optical devices and spatiotemporal control of ultrashort optical pulses, but no one measures it. Using the dispersion of high-frequency linear electro-optic coefficients of congruent LiNbO3 crystal, the author has obtained the wavelength dispersion of the high-frequency quadratic electro-optic coefficients and the dispersion of composite photoelastic coefficients .
