Abstract

Our research involves the application of sophisticated laser pulse sequences to extract dynamic information on gas phase collisional and relaxation processes not measurable by other means. We will discuss the use of shaped pulses that improve sensitivity by exciting a molecule regardless of its Rabi frequency as well as providing a uniform inversion over the pulse bandwidth. Applications to monitoring velocity-changing collisional dynamics and generating large vibrational population inversions will be presented, as will experimental methods to extend these sequences to more complex molecules, where velocity selection and frequency resolution are not equivalent.
