Abstract
An electrooptic device having a simple structure that can efficiently increase deflection of a beam is provided. The device includes: an electrooptic crystal (11) having an electrooptic effect; an electrode pair of a positive electrode (12) and a negative electrode (13) for generating an electric field inside the electrooptic crystal; and a power source for applying a voltage between the electrode pair so as to generate a space charge inside the electrooptic crystal. With this arrangement, by using a simple structure, a change in a deflection angle is temporally rapid, and a large deflection angle that can not be obtained by a conventional electrooptic crystal prism can be acquired at a low applied voltage.
