Big solar furnace as pumping source for high power lasers

For effective conversion of the energy of the concentrated solar flux of 1 MW Big Solar Furnace of the Scientific and Production Association "Physics-Sun" (Tashkent) with focal spot size of about 40 cm into the coherent laser radiation, the several designs of the multi-element secondary concentrators for various active mediums with different thermal and optical characteristics were considered. For calculations of parameters of secondary concentrators the Ray tracing and Monte-Carlo methods were used and the numerical experiments were performed.
