Source of radiation for diagnostics of the divertor plasma on the ITER facility

An optical scheme of a diode-pumped, two-channel, solid-state laser is considered. The scheme is destined for diagnostics of the physical processes occurring in the divertor area of the tokamak-type fusion facilities by the method of Thomson scattering and has been developed on the basis of modern engineering and technological advancements made in powerful pulse-periodic laser systems. The schemes for the laser diode pumping of the active elements are considered, and the results of thermal and hydraulic calculations of a pumping module are presented. The results of the energy calculation confirm the feasibility of a laser system with technical parameters meeting the requirements of a task assigned.
