Paper Abstract

Based on the theory of the conical refraction, the hollow conical laser will appear at the internal of the biaxial crystal when laser traveling along one of the axis of the biaxial crystal. The hollow conical laser is different from the solid laser; all of its energy is disturbing on the cone that is similarly the funnel. The study of the produce and control of the hollow conical laser will provide the theoretical and technique basis for its application. In this paper, Based on the matter equation of anisotropies and the propagation law of light in the biaxial crystal, the production of the conical laser was theoretically analyzed and calculated in detail, and the cone angle equation of the hollow conical refraction was obtained, which provided the control and modulation of hollow conical laser with theoretical bases. The cone angle of the conical laser was adjusted by changing the convergence angle of the incidence laser; the all-beam, large-angle and dynamic laser scan was realized by controlling emergent conical laser with varifocal system.
