| Abstract: | In this work, the magnitudes of the critical voltages are determined for various mutual orientations of the optical axis of the crystal, the vector of the applied electrical field intensity, and the wave vector of the optical radiation being modulated both for the linear and quadratic electrooptic effects in BaTiO3 crystals. It is shown that the critical voltages are considerably lower for the linear electrooptic effect than for the quadratic. The minimal critical voltage which ensures a modulation depth of 100% for the linear electrooptic effect is equal to 30 V.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, Vol. 16, No. 7, pp. 35—38, July, 1973. |
