K2 Photonics

Founded in 2023 as a spin-off from ETH Zurich, K2 Photonics is a Swiss photonics company specializing in next-generation ultrafast laser technology for precision sensing and measurement applications. The company focuses on compact femtosecond lasers and optical frequency comb solutions designed to deliver laboratory-grade performance in practical industrial and scientific environments. Its core innovation is a single-cavity dual-comb laser architecture that generates two highly correlated pulse trains from a single oscillator, simplifying system design while improving stability, precision, and scalability.

K2 Photonics develops laser platforms for applications including spectroscopy, semiconductor inspection, gas sensing, pump-probe measurements, precision ranging, material analysis, and time-frequency metrology. The company emphasizes ultra-low noise performance, high-speed optical delay scanning without moving parts, and compact system integration suitable for OEM and industrial deployment.

The founding team combines deep expertise in ultrafast optics, photonics engineering, and commercialization, with leadership drawn from advanced laser research at ETH Zurich. The company is also advised by renowned laser physicist Ursula Keller, whose work in ultrafast lasers helped establish the foundation for many modern femtosecond laser systems.

In 2025, K2 Photonics announced a seed funding round to accelerate commercialization and global deployment of its dual-comb laser technology.
