Claims

[Scope of utility model registration request]

a first surface, a second surface opposite the first surface; a third surface coupled to the first and second surfaces and serving as an entrance surface for receiving incident light; a third surface opposite the entrance surface; an acousto-optic medium having a fourth surface serving as an exit surface, and fifth and sixth surfaces connected to the first to fourth surfaces and facing each other; and a transducer,
The transducer is an acousto-optic transducer that propagates an ultrasonic wave in the direction of a second surface in the acousto-optic medium, and modulates or polarizes incident light that is incident on the acousto-optic medium through the incident surface by the ultrasonic wave. In the element, at least one of the six surfaces of the acousto-optic medium is provided with thermal equalization means for equalizing the temperature distribution in the traveling direction of the ultrasonic wave in the acousto-optic medium. Characteristic acousto-optic elements.
