| Research Abstract |
A two color laser interferometer using short wavelength far-infrared laser sources has been developed for high performance operation on the Large Helical Device and for future burning plasma experiments such as ITER. Through investigation of THz laser sources, we have achieved high power simultaneous oscillations at 57.2 μm and 47.6 μm of a CH_3OD laser. We have developed a new two color laser interferometer, and confirmed its original function, vibration subtraction. A new Photo-elastic Modulator (PEM) was developed for a polarimetry, and we confirmed that the achieved angle and time resolutions satisfy ITER diagnostic requirements.
