Collinear acousto-optical tunable filter and acousto-optically tunable laser
Patent
·
OSTI ID:4047806
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-optical filter between the mirrors of a laser is also described.
