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.
