Abstract
A five-channel far-infrared (FIR) laser interferometer was designed to measure the line averaged electron density on the Experimental Advanced Superconducting Tokamak (EAST). An improved deuterium cyanide laser was used as the light source. The waveguides were used because of a long distance between the laser and the detectors. Each part of the interferometer is described in detail.
