Abstract
A collinear, acousto-optical, tunable filter is described. A well-collimated, polarized beam of light enters a crystal of Tl.sub.3 AsSe.sub.3. A sound wave generated in the crystal collinear to the light rotates the plane of polarization of the light. A method of analyzing a light spectrum is also disclosed. An acousto-optically tunable laser employing an acousto-optical filter between the mirrors of a laser is also described.
