ACTIVE ACOUSTO-OPTIC MODULATORS.
Abstract
In recent years there has been considerable interest in the use of acousto-optical interaction phenomena for the modulation, deflection, and Q switching of lasers. This has been due principally to the development of new materials and techniques which have made such devices competitive with the better established mechanical and electro-optic methods. Typically an acousto-optic system consists of an interaction medium onto which a piezoelectric transducer is bonded, and an R.F. power source which excites the transducer producing the required acoustic waves. This report discusses a simplified alternate approach to this problem in which an active ultrasonic oscillator excited by a DC voltage source serves as both the interaction medium and the generator of the ultrasonic waves.
