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 …
