Overview

Cycle is a German high-tech company that develops and manufactures precision timing and synchronization equipment based on ultrashort pulse lasers. Founded in 2015 as a spin-off from the DESY research institute in Hamburg, the company commercializes femtosecond laser technology and optical timing distribution systems that synchronize radiofrequency and optical equipment with sub-femtosecond resolution. Its product portfolio includes femtosecond fiber lasers (SONATA, SOPRANO), optical timing distribution and synchronization platforms (PULSE, WAVE), frequency and time generation systems (RBX, MTGEN), and a range of timing modules such as the TIC time interval counter, BOMPD balanced optical microwave phase detector, and E-SYNC locking electronics. These products serve scientific facilities and industrial applications in materials research, life sciences, industry, and space. Cycle is an official partner of ESA and supplies next-generation time distribution systems for the DeepSpace ground stations. The company is located at the Start-Up Labs Bahrenfeld on the DESY campus in Hamburg and has grown to over 20 employees, serving more than 30 customer facilities with over 40 systems installed.

History

Cycle was founded in 2015 as a spin-off from the DESY research institute in Hamburg, Germany, by renowned researcher Prof. Franz X. Kärtner. The company was established to commercialize cutting-edge research in femtosecond laser technology and precision timing distribution. In 2020, Cycle was awarded a contract as an official partner of ESA to supply the next generation of time distribution systems for the DeepSpace ground stations. In 2021, the company moved into new office and lab facilities at Start-Up Labs Bahrenfeld on the DESY campus in Hamburg. As of its company page, Cycle has grown to over 20 employees, serves more than 30 customer facilities, and has installed over 40 systems worldwide. The company continues to advance its technology in close cooperation with leading international institutions.
