Abstract

A two-color interferometer system using 48-and 57-μm CH₃OD lasers pumped by a continuous-wave (cw) 9R(8) CO₂ laser have been developed to measure electron density profiles of large plasma devices. To test this system, the Michelson interferometer of one channel has been constructed on a test bench. We have obtained preliminary interference signals from the two-color interferometer system.
