Radiantis was created with the mission to enrich the photonics market with state-of-the-art, robust, and easy-to-use frequency conversion systems. Based in Castelldefels, Barcelona, the company was founded in July 2005 as a spin-off from ICFO-Institut de Ciències Fotòniques and ICREA-Institució Catalana de Recerca i Estudis Avançats.
The company strives at enabling cutting-edge advances at the frontiers of scientific research and technological innovation. Since its inception, Radiantis has developed a wide range of Optical Parametric Oscillators and other frequency conversion systems in various operating time scales from ultrafast femtosecond (fs) and picosecond (ps) to continuous-wave (cw) regime, which has positioned it as the only company in the sector with this capability worldwide.

Radiantis is made up of valuable human capital of which the company is proud. This capital encompasses a talented and dedicated team across all areas of activity in the company, from R&D and production to administration, sales and marketing, procurement and finance.
In 2025, Radiantis became part of the Hawthorn Photonics Group, expanding our global reach and technical expertise. This next chapter strengthens our ability to collaborate internationally and accelerate innovation across the photonics community.
