Abstract
Fundamental mode operation along with high output power is a major challenge for an electrically pumped VECSEL (EP-VECSEL) suitable for passive modelocking. We present an experimental study on the influence of the intermediate DBR reflectivity on the beam quality and the output power of EP-VECSELs. For designs with reflectivities of 90%, 82% and 71% the highest possible power for the best achievable beam quality was 15.1 mW (M2 = 1.1, 82% device). We can demonstrate that a correctly chosen intermediate DBR reflectivity is necessary for both good beam quality and high power, and that a trade-off in power has to be accepted.
