• A CO_2 laser interferometer system has been developed in JT-60U. The system has a toroidally tangential chord for electron density measurement on large tokamaks. There are four major topics as follows; (1) the investigation of conditions for the tangential interferometry in large tokamaks, (2) the development of a CO_2 (10.6 μm)/IR-HeNe (3.39 μm) laser interferometer, (3) the development of a dual CO_2 laser interferometer with a wavelength combination of CO_2 (10.6 μm)/CO_2 (9.27 μm), and (4) the development of a very high resolution phase comparator which is designed to have a phase resolution of 2π/12,800 rad for 2 MHz Signals. The results achieved show that the novel dual CO_2 System is feasible for not only JT-60U but also future large devices like ITER.
