We have grown several Cr,Tm:YAG and Cr,Tm,Ho:YAG-crystals in order to optimize the dopant concentrations. We observered slope efficiencies of 1.8% for Cr,Tm:YAG and 4% for Cr,Tm,Ho:YAG. Output energies >3 Joules were measured for both crystals. The dynamical behaviour of Tm- and Ho-lasers is very different and is explained by a simple model. The influence of the dynamics on the Q-switch performance of Cr,Tm:YAG and Cr,Tm,Ho:YAG is analyzed.
