    Abstract

    A computer simulation of the dynamics of the Er3+ 3 um cw crystal laser considering the full rate-equation scheme up to the 4F7/2 level has been performed. The influence of the important system parameters on lasing and the interaction of these parameters has been clarified with multiple-parameter variations. Stimulated emission is fed mainly by upconversion from the lower laser level and in many cases is reduced by the quenching of the lifetime of this level. However, also without upconversion a set of parameters can be found that allows lasing. For a typical experimental situation we started with the parameters of Er3+:LiYF4. In addition also the host materials YAG, YAlO3, YSGG, and BaY2F8 as well as the possibilities of codoping are discussed.
