Dissociation kinetics of diatomic molecules under laser excitation of low vibrational levels and effective heat transfer
Abstract
The paper presents an analysis of the effect of initial conditions and the shape of the laser pulse on the dissociation kinetics of diatomic molecules over the entire time interval from the initial stage to the establishment of the steady state. It is shown that dissociation can be initiated by external radiation more effectively at low translational temperatures than at high temperatures, the exponential shape of the pumping pulse being most efficient for this purpose. This efficiency is explained by the intense 'heating' of the vibrational degrees of freedom which occurs at the initial stage; this 'heating' is then sustained by prolonged but less intense radiation at the tail of the pulse.
