Propagation of chirped sinh-Gaussian beams in uniaxial crystals orthogonal to the optical axis

摘要

This article includes intensity evolution and phase change of chirped sinh-Gaussian(CSG) beam propagating in uniaxial crystal orthogonal to optical axis. Received field expression is calculated utilizing Huygens-Fresnel integration. We see that chirped parameter brings decentered intensity distribution. By adjusting the decay factors, higher peak intensity can be obtained at the receiver side. Broken phase at near field is corrected at phase field. Phase change and number of circles can be controlled by decay factor and chirped parameter. We hope that our results are helpful for scientist working on optical tracking.
