Outline of Final Research Achievements

This research project aims to realize highly advanced coherent anti-Stokes Raman scattering spectroscopy with capability of quantum-state selection by implementing coherent control methodology, such as chirped pulse adiabatic passage. In this project, we have succeeded in up-grading the frequency-modulated coherent nanosecond pulsed light source that has been developed in our research group, to achieve higher stability and controllability. We have also conducted theoretical consideration on the application of this novel pulsed light source to the complete population transfer to highly lying quantum state via rudder-climbing Raman excitation by multiple chirped pulses and quantum-state specified enantio-selection via combined use of microwave radiation and chirped pulses.
