Simulation on temperature rise of multilayer dielectric coating with vortex beam irradiation
The transmission model of vortex beam within multilayer dielectric coating has been established, and the temperature property of multilayer dielectric coating irradiated by optical vortex has been discussed. The results show that the temperature property is closely related to the incident plane of vortex beam. When irradiated by the initial plane of optical vortex, the region of temperature rise of coating was focused on the incident center. When irradiated by the optical vortex with a certain transmission distance in space, the temperature rise regions of coating spread on both sides of the incident center. When the transmission distance is far enough, the maximum temperature decreases with the increase of transmission distance. Moreover, the maximum temperature increases as the topological charges increase within a certain transmission distance. Nevertheless, the maximum temperature decreases as the topological charges increase when the transmission distance is far enough.
