Vexlum

Vexlum describes itself as a spin-off from the Optoelectronics Research Centre at Tampere University of Technology in Finland. The company says it builds on long-standing expertise in VECSEL technology, including optoelectronic materials, scalable manufacturing processes, and application-specific laser systems engineering.

Its focus is semiconductor laser technology based on VECSELs, which it presents as a platform combining semiconductor lasers with optically pumped external-cavity disk lasers. The company states that recent breakthroughs include the use of VECSELs for quantum technology applications. Its products are described as high-power, low-noise, single-frequency lasers with broad wavelength coverage in the visible and near-infrared, positioning Vexlum as a supplier of laser and photonics hardware relevant to quantum-technology systems.
