Abstract

PURPOSE:To extend the length of an optional path and interference length between an ultrasonic wave and light, and to improve diffraction efficiency by reflecting incident light repeatedly and providing an electrode for a transducer along the optical path. CONSTITUTION:The incident light 6 while reflected repeatedly in an acoustooptic medium 1 passes through the acoustooptic medium 1 by a distance larger than its length (l) and exits. For the purpose, the electrode 3 for the transducer is provided along the optical path to cause the interference of the ultrasonic wave, thereby making the incident light and ultrasonic wave to interfere with each other by a longer distance than before. Consequently, the diffraction efficiency of the incident light 6 is remarkably improved.
