Collection optics design for KSTAR Thomson scattering system

The collection optics designs are described for the Thomson scattering diagnostic of the Korea superconducting tokamak advanced research (KSTAR) device. The optical systems collecting the light emission induced through the interaction between the plasma electrons and a laser beam are key components for the Thomson scattering system. A duo-lens system was examined, and the final optical designs were derived for Thomson scattering diagnostic of KSTAR.
