Passively mode-locked femtosecond VECSELs with high average output power

Abstract

The broad gain-bandwidth and the high output powers make vertical-external-cavity surface-emitting lasers (VECSELs) promising candidates as femtosecond laser sources. Besides an effective design of the gain structure, the major challenges for high power VECSELs are the thermal management of the chips as well as the homogeneity of the epitaxial growth. In this work, we present results of passively mode-locking of our highly efficient VECSELs and demonstrate femtosecond operation with record output powers and pulse energies. At a repetition rate of 1.7 GHz, we achieved nearly transform-limited pulses with 682 fs duration and an average output power exceeding 5 W.
