| Research Abstract |
In this study, we have developed a new quantum control scheme utilizing the effective decomposition of quantum space brought by the irradiation of intense CW-laser fields, which makes it possible to solve three major problems in applying coherent laser control scheme to various molecules, i. e., (1) elimination of dissipation process, (2) manipulation of time scale of control process, (3) clarification of physical picture for quantum control of multi-level system. We have successfully applied the present method to Thiophosgene molecule and shown that the dissipation process can be effectively eliminated while the system dynamics can be controlled by well-established conventional control schemes such asπ-pulse method.
