Description
A single-channel vertical interferometer system and a multichannel tangential interferometer/polarimeter system will be constructed on the Korea Superconducting Tokamak Advanced Research device. A vertical system will be used mainly for a density feedback control and a tangential system will be used for getting electron density profile along the radial direction of plasma. Three 118.8 μm methanol lasers optically pumped by 9.7 μm carbon dioxide lasers are implemented as beam sources. The optical system including optics inside the retractable cassette has been designed in the consideration of long beam paths in a narrow diagnostics port. In addition to the shifted phase compensation, focusing mirrors will be used to minimize the deflection error since large deflection of the tangential beam is expected in such a long beam path
