Paper Abstract

In the early nineteenth century, People paid attention to the phenomenon that the biaxial crystal could produce conical refraction. A bunch of solid quasi-monochromatic beam can be considered as the light source, when the laser propagates through the biaxial crystal, the "funnel-shaped" hollow cone laser can generate inside the biaxial crystal or outside. This paper is based on this point to study the hollow cone laser that produced by biaxial crystal. In this paper, the ring size of the conical refraction can change with incident angle from refractive indices ellipsoid of biaxial crystal. Through computer simulation, the characteristics biaxial crystal produce conical refraction can be analyzed. When laser propagate through the biaxial crystal, the phenomenon of absorption and dispersion is appeared, and it will affect on the transmission quality. According to the absorption and dispersion properties of conical refraction, the spatial coherence decrease when laser propagates through the biaxial crystal. The beam propagation direction will change with refractive index, which will cause the change of optical path length. In addition, the experiments and theoretical study can achieve the same results. This paper also discuses the hollow cone laser can be applied to optical switching, radar scanner, copier, scanner and other applications.
