This work demonstrates a new simulation technique, which combines the previously published Dynamic Mode

Analysis with the coupling of arbitrary sets of rate equations. Those arbitrary sets include the representation

of gain media, which state population is influenced by interionic mechanisms. Especially the state population of

Er:YAG is strongly influenced by upconversion and cross relaxation, which impacts the population inversion and

the generated heat load. Therefore, the simulation of a resonator based on 50%-doped Er:YAG is performed and

compared to experimental results. The accuracy of the presented technique is pointed out by a fine agreement

between simulation and experiment with respect to gained cw output power and slope efficiency. Moreover, a

finite element analysis of the heat load and the 3-dimensional population inversion in the crystal is illustrated.
