Abstract

Volumetric thermal gratings were created in liquid and gaseous media and were used to efficiently deflect laser beams. In gaseous media, a low-input energy requirement and high switching efficiency make this type of switch a good candidate for a practical device. The switch is scalable to large apertures and has low insertion loss.
