Abstract
After a brief review of studies of infrared (IR) multiphoton dissociation (IRMPD) of diatomic molecules, we discuss recent results using a chirped laser pulse. Nonlinear dynamical analysis of the chirped process shows that the dynamics is different from that of constant-frequency case and can be described in terms of "bucket dynamics", in which a cluster of trajectories are trapped in a bucket which moves up steadily in phase space. This mechanism explains the efficiency of the chirped process in inducing dissociation, resulting a threshold field strength orders of magnitudes lower than that of the constant-frequency case. We present quantum results of chirped processes, compare them with the classical ones, and discuss the significance of the similarities and differences.
