Paper Abstract

Kinetic modelling of a short-pulse optically pumped hydrogen fluoride laser has been undertaken. This work utilizes scaling laws to obtain many of the rate constants describing the numerous energy transfer reactions. Because of the numerous differential equations and energy exchange reactions that must be considered in a complete model, a truncated version has been constructed which includes the processes which are most important in the first several nanoseconds: an optical pump term which includes saturation effects and rotational relaxation kinetics during the buildup of the laser pulse. This model demonstrates the importance of rotational relaxation processes to the efficiency with which energy is coupled into the laser.
