Laser Optic

The possibility of an approximate description of a multimode beam of a fiber laser in the Zemax modeling system for the development of an optic system of a laser head is shown. There are developed and manufactured optic units of a laser head taking into account characteristic peculiarities of radiation of high-power fiber lasers. The possibilities are shown the developed optic system in the technology of laser polishing by the remelting of a sample surface made of stainless steel of type 1540-00.
