Paper Abstract

The paper discuses the influence of cross-relaxation parameter on the characteristics of the sensitized photon avalanche. A system Pr3+ as activator ion and Yb3+ as sensitizer ion were considered for the avalanche process. By numerical modelling of a system of rate equations, time dependencies and pump rate dependencies of populations of energy levels were calculated for three different values of cross-relaxation rate. Correlation between cross-relaxation rate and threshold value of pump intensity was established.
