Abstract
This invention relates to deflection cells for laser beams. A deflection cell according to the present invention essentially comprises a deflector such as of the 'acoustooptical' type, to deflect a low-power incident laser beam, and a system to make that deflected low-power incident beam, in a nonlinear Brillouin diffusion medium 11 like a gas such as methane (CH.sub.4), xenon, sulfur hexafluoride (SF.sub.6), or a liquid such as carbon disulfide (CS.sub.2), acetone, work with a high-power laser pump beam, forming a nonzero angle '.theta.' with the deflected beam. Application, in particular, to telemetry and missile guidance for which the laser beam used as reference should be able to undergo orientation changes which are quick and in a large angular field.
