A detailed investigation of a Generalized Hermite cosh-Gaussian beam propagating in uniaxial crystals orthogonal to the optical axis

Abstract

In this paper, we study the propagation properties of a Generalized Hermite cosh-Gaussian beam (GHCGB) in uniaxial crystals orthogonal to the optical axis. The analytical propagation equation for the GHCGB at the receiver plane is derived based on Huygens-Fresnel integration. Some analyses are investigated to illustrate the influences of variation in crystal refractive indices, source beam parameters and propagation distance on the beam intensity profiles. Results indicate that a GHCGB would better preserve its intensity profile nearly invariant for a short propagation distance and larger source beam parameters, whereas, the anisotropy of the uniaxial crystal has a significant effect on intensity evolution with increasing the propagation distance. In addition, beam width of output beam can be controlled by adjusting the source beam parameters and uniaxial crystals. According to the results that it will be useful for the control of optical particle.
