Trends, Challenges and Applications of Ultrafast VECSELs

Semiconductor laser are extremely versatile laser systems offering
wavelength-tunability, high-power, and the potential for cost-efficient mass-
production. Profiting from these qualities, ultrafast Vertical External Cavity Surface Emitting Lasers (VECSELs) have emerged in the last decades as a unique source of GHz-repetition rate femto-second pulses. In this presenation I will present an overview of the technology and its state-of-the-art as well as potential future directions
