Outline of Final Research Achievements

In multilaser Thomson scattering systems, including the Large Helical Device (LHD) Thomson scattering system, flexible operations are possible. The beam packing method in which we have used previously, has some disadvantages because there are some differences among the laser beam paths. For example, unexpected experimental error is induced due to the beam path difference.
Therefore, we have developed a new coaxial beam merging system using a polarization control technique for the LHD Thomson scattering system, and successfully applied to our three laser system
