The Evolution of Vortex Laser in Organic Crystal DSTMS

A study of the evolutionary mechanism of vortex beams in nonlinear organic crystal DSTMS has been initially investigated, which shows that the nonlinear transmission effect can change the light intensity distribution of vortex beam to a large extent. The generalized Gaussian beam decomposition method is utilized to simulate and analyze the light intensity distribution of the LG beam before and after passing through the medium with Kerr-like effect, showing that the Kerr medium affects the incident LG beam by producing LG beams with different radial modes. Moreover, the effect of different polarization of the incident vortex light on vortex mid-infrared laser transmission in DSTMS, demonstrating the effect of nonlinear transmission on the LG beam is investigated.
