ABSTRACT:
An optical deflection device for redirecting and/or focusing a high-power collimated beam of light, comprising an optically transparent gas-filled hollow sphere, and a plurality of gas-filled lenses positioned within the sphere. When photorefractive or optically non-linear gases are used within the sphere and lenses, a second beam of light made to travel along the path of the original beam, will result in a local change of refractive index of the gas, thereby altering the path of the original beam. In separate embodiments thereof, the lenses may be mechanically repositioned, the internal pressure of the sphere varied, or a combination of these and the foregoing accomplished.
