Degradation studies of a VECSEL gain structure whitepaper

The degradation of the gain structure of a red-emitting Optically Pumped Semiconductor (OPS) Vertical External-Cavity Surface-Emitting Laser (VECSEL) pumped by an opus 532 laser emitting at 532nm is presented. The exceptional, long-term power stability of the opus 532 allows accurate monitoring of the performance of the VECSEL over several tens of hours, thereby helping to better understand the observed degradation effects within the VECSEL material.
