»We produce world-leading timing equipment that synchronizes RF and optical equipment to each other with sub-femtosecond resolution.«

– Prof. Franz X. Kärtner, Cycle Founder

Our Mission

Cycle is a young high-tech company that manufactures world-leading precision systems based on ultra-short pulse lasers. The DESY spin-off company was founded in 2015 by renowned researcher Prof. Franz X. Kärtner.

For customers in science and industry we manufacture unique products that enable new applications in biology, material analysis and precision metrology. Our systems are used in research facilities around the world, and as an official partner of ESA we supply the next generation of time distribution systems for the DeepSpace ground stations. We are constantly advancing our technology in close cooperation with leading international institutions.
