We report the first observation, to our knowledge, of the electro-optic effect in total internal reflection. Light from a He-Ne laser is incident through a high-index prism upon a KDP crystal to which a pulsed electric field is applied through coated-surface electrodes. At the critical angle for total internal reflection, a narrow resonance in the modulated reflected light is observed. This effect is well described by solving the standard boundary-value problem of nonlinear optics.
