Abstract

We compare the single-frequency performance of a 780 nm vertical-external-cavity surface-emitting-laser (VECSEL) under top-hat and Gaussian pump profiles with the former yielding an 84 % increase in output-power (880 mW) with a linewidth of 5.92(1) kHz. The Gaussian-system is utilized in Rb-spectroscopy.
