Claim:
1. A visual dazzler system for temporarily disorienting subjects to light projected from the system, comprising a case containing and delivering electrical power to a light beam source and also containing a solid diffuser element of transparent refractive material optically coupled to receive a light beam from the beam source at tangential or near tangential incidence such that the received light beam is partially reflected and partially refracted multiple times within the diffuser element and thereby is projected radially outward from the diffuser over a wide distribution to any of one or more subjects in line of sight of the projected light; wherein the diffuser element comprises a ring torus of solid transparent refracting material, the torus characterized by a surface of revolution generated from rotation of a closed plane curve about an axis coplanar with, outside of, and proximate to the curve, the light beam source positioned relative to the torus such that a light beam from the source is directed substantially along the axis of the torus, the beam having a width so as to be coupled into the torus and partially reflected and partially refracted therein at the torus surface, the torus having a reflective coating on a rear source-side surface located be and the extent of the incident beam such that light emitted from the torus diffuser is tailored to have a specified distribution pattern.
