Study of the electro-optical transformation of linearly polarized Bessel beams propagating along the optic axis of an anisotropic DKDP crystal

摘要

This paper presents a numerical and experimental study of the electrically controllable transformation of linearly polarized Bessel laser beams propagating along the optic axis of an anisotropic DKDP (deuterated potassium dihydrophosphate) crystal. Based on numerical modeling and experiment, it is shown to be possible to vary the intensity distribution at the output of an anisotropic crystal by varying the wavelength of light at a fixed length of the crystal. The propagation of a plane-polarized zeroth-order Bessel beam is numerically modeled along the axis of a DKDP crystal in the presence of an applied electric field, which causes the appearance of induced biaxiality of the electro-optical crystal. The dynamic transformation of Bessel beams when an electric field is applied along the optic axis of an anisotropic crystal is experimentally studied. (C) 2018 Optical Society of America
