The purpose of the conference is to highlight the recent progress in the field of optically pumped semiconductor thin disk lasers, such as vertical external cavity surface emitting lasers (VECSELs) and the more novel concepts such as MECSELs, MIXSELs, … . In optically pumped semiconductor thin disk lasers, the light is emitted perpendicular to the semiconductor gain media layers and the gain chip is placed in an external cavity. This offers mode control with excellent transverse beam quality and multi-Watt output power levels. The external cavity also enables the integration of elements for nonlinear intracavity frequency conversion, wavelength tuning, or passive modelocking.

Compared to external-cavity diode-pumped solid-state lasers, semiconductor lasers operate in much broader spectral regions owing to wavelengths versatility of semiconductor bandgap engineering. Direct continuous-wave (cw) emission from VECSELs has been demonstrated for the entire wavelength range covered by compound semiconductors, extending from blue to mid-IR. Moreover, efficient intra-cavity nonlinear frequency conversion allows to further broaden spectral coverage, reaching ultra-violet and terahertz emission, promoting VECSELs to a status of the most versatile laser type.

High-power cw VECSELs have been widely used in medicine, spectroscopy, or for pumping of solid-state lasers and new applications are emerging taking advantage of the unique features they offer. For example, owing to their low-noise properties, high-power, and single-frequency wavelength-tunable operation, cw VECSELs are increasingly used in quantum-technology applications, such as ion-trapping or quantum-sensing. Furthermore, ultrafast VECSELs and MIXSELs are opening new application opportunities in high-resolution spectroscopy, frequency metrology, and multiphoton microscopy.

A selection of invited papers will provide a comprehensive overview of the latest progress in this fast-developing field. In addition, contributed papers are solicited on all aspects of VECSEL related research, including:
