Two color laser diagnostics using terahertz laser sources are under development for a high performance operation of the Large Helical Device and for future fusion devices such as ITER. So far, we have achieved high power laser oscillation lines simultaneously oscillating at 57.2 and 47.7 μm by using a twin optically pumped CH(3)OD laser, and confirmed the original function, compensation of mechanical vibration, of the two color laser interferometer. In this article, application of the two color laser diagnostics to the ITER poloidal polarimeter and recent hardware developments will be described.
利用太赫兹激光源的双色激光诊断技术正在为大型螺旋装置的高性能运行以及未来的聚变装置（如国际热核聚变实验堆ITER）而研发。到目前为止，我们通过使用双光泵浦CH(3)OD激光器实现了在57.2和47.7μm同时振荡的高功率激光振荡线，并证实了双色激光干涉仪的原始功能——机械振动补偿。在本文中，将描述双色激光诊断技术在ITER极向偏振计中的应用以及近期的硬件进展。
