We investigate the phenomenon of the transverse breaking of symmetry of Gaussian lasers transmitted through dielectrics, showing for which incidence conditions and beam parameters it can be observed in optical experiments. The numerical analysis, done by using the integral form of the transmitted beam at the lower interface of a dielectric prism, shows, for incidence approaching the critical region, a laser planar trapping. By using an analytic approximation for the intensity of lower transmitted beam, we model the wave front curvature by a closed expression which depends on the refractive index, on the geometrical properties of the dielectric block, and, finally, on the incidence angle of the incoming beam. The analytic formula shows an excellent agreement with the numerical analysis and it could be useful in future experimental implementations.

激光平面陷印

我们研究了通过电介质传输的高斯激光对称性横向破坏的现象，显示了可以在光学实验中观察到的入射条件和光束参数。通过使用介质棱镜下界面处透射光束的积分形式进行的数值分析显示，对于接近临界区域的入射，激光平面捕获。通过对较低透射光束的强度使用解析近似，我们通过一个闭合表达式对波前曲率进行建模，该表达式取决于折射率、介电块的几何特性，最后取决于入射光的入射角光束。解析公式与数值分析非常吻合，可用于未来的实验实施。
