Dynamic model of high-pressure rare-gas excimer lasers

Abstract

The dynamic behavior of the high-pressure rare-gas VUV excimer systems is examined. It is found that the collisional coupling of the excited singlet and triplet manifolds in combination with the losses arising from photoionization play a vital role in determining the over-all performance. The proposed mechanisms provide a unified description of both the pressure dependence of the stimulated output and the observed pressure shift of the stimulated spectrum in xenon. Numerical values of the relevant parameters are given.
