Abstract

The influence of an intra-cavity anti-reflection coating on the switch-on dynamics and the power input-output characteristic of a vertical-external-cavity surface-emitting laser (VECSEL) system are investigated. The experiments show a significantly higher threshold and slower switch-on dynamics for anti-reflection coated systems. These differences originate in the changes in the mode strength at the active medium due to the more or less pronounced sub-cavity. The presented simulations based on microscopic calculations are in good qualitatively agreement with the experiments.
