Influence of vibrational relaxation on energy characteristics of a laser pulse in a molecular amplifier

Characteristics of the interaction of a laser pulse with a molecular medium are analyzed theoretically in the case when vibrational relaxation takes place in the ground and excited electronic states. The diffusion approximation is used to describe the relaxation transitions. The same approximation is employed in an analysis of the establishment of the limiting steady-state energy of a pulse in a molecular laser amplifier with linear nonresonance losses.
