| Outline of Final Research Achievements |
In this study, the possibilities of Q-switched laser action in cholesteric liquid crystal (ChLC) lasers was investigated. To demonstrate Q-switched lasing, the electro-optic effect with fast response times in the ChLCs must be achieved, and thus I focused on the speeding-up technique of the response characteristics. In the process, a new fast response component was discovered, which was the microscopic molecular motion separated by removing the motion of the helical elongation. At this time, the alignment method using a shear stress was required to orient the helix axis in the cell-plane direction.
