Abstract
The dependence of the output-energy efficiency and thermal load of an Er:YAG laser on the spectrum of exciting flash-lamp light has been mea sured. In particular, the influence of the direct and cross-relaxation pumping process has been studied. For pump pulses of 400 mu s cross-r elaxation pumping processes provide four times the efficiency and 1.5 times less thermal load normalized to fixed output energy.
