Radiative and kinetic mechanisms in bound-free excimer lasers

An interactive kinetic model for bound-free excimer lasers is described, with particular emphasis on the electron beam pumped rare gas systems. Important kinetic processes and the interaction of the photon field with excited states are examined in detail. Application of the model to the xenon and krypton oscillators yields results which are in good agreement with experimentally observed quantities. It is found that the collisional coupling of the excimer singlet and triplet manifolds in combination with the losses arising from photoionization play an important role in determining the performance. Numerical values of the parameters used in the computational model are given.
