We present a comparison of epitaxial designs for barrier pumped vertical external-cavity surface-emitting lasers in the red spectral range. The VECSEL chips are grown by metal-organic vapor-phase epitaxy as GaInP/AlGaInP multi-quantum well structures

Three years after the first realization [1] of the vertical external-cavity surface-emitting laser (VECSEL), passive mode locking by inserting a semiconductor saturable absorber mirror (SESAM) into the cavity was presented [2]. Besides the advantageo

Vertical External Cavity Surface Emitting Lasers (VECSELs) VII.
Since 2000, semiconductor saturable absorber mirrors (SESAMs) have been used to realize mode locking of vertical external-cavity surface-emitting lasers (VECSELs), achieving femtosecond pulse durations, GHZ repetition rates and several Watts of avera

We present a strain-compensation design for non-resonantly pumped vertical external cavity surface-emitting lasers for emission in the red spectral range around 665 nm. Here, the VECSEL chip is based on a metal-organic vapor-phase epitaxy grown (Ga x

We report a continuous wave operation of a quantum-well and multi-pass-pumped AlGaInP based red vertical-external cavity surface-emitting laser emitting at 660 nm. The laser output power was 1.5 W with a slope efficiency of 35 %. The critical role of

We present a passively mode-locked semiconductor disk laser (SDL) emitting at 650nm with intra-cavity second harmonic generation to the ultraviolet (UV) spectral range. Both the gain and the absorber structure contain InP quantum dots (QDs) as active
