High power 739 nm VECSELs for future Yb+ ion cooling
High power 739 nm VECSELs for future Yb+ ion cooling
We present an operational characterisation of a vertical-external-cavity surface-emitting laser (VECSEL) emitting around 739 nm with over 150 mW in a single fundamental spatial mode. Results show that the laser is capable of oscillating on a single cavity axial mode at 740 nm for up to 22 mW. Tuning of the optical emission is shown to reach 737.3 nm. Furthermore at best performance, the laser exhibits a slope efficiency of 8.3%, and a threshold power of1.27 W for an output coupler reflectivity of 98%.

Abstract
We present an operational characterisation of a vertical-external-cavity surface-emitting laser (VECSEL) emitting around 739 nm with over 150 mW in a single fundamental spatial mode. Results show that the laser is capable of oscillating on a single cavity axial mode at 740 nm for up to 22 mW. Tuning of the optical emission is shown to reach 737.3 nm. Furthermore at best performance, the laser exhibits a slope efficiency of 8.3%, and a threshold power of1.27 W for an output coupler reflectivity of 98%.
