The Cycle GmbH is a spin-off of the Ultrafast Optics and X-rays Group at the Centre for Free-Electron Laser Science CFEL at DESY. The company supplies innovative products that use ultrafast laser technology for scientific and industrial applications, such as synchronisation units for large facilities with an accuracy within a femtosecond.

Cycle GmbH develops and produces femtosecond synchronization systems based on fiber optic technology and ultrashort pulsed lasers. The special feature of these systems is that they allow the synchronization of a number of optical and microwave instruments across several kilometers with the precision of femtoseconds. These unique features are of vital importance for the synchronization of large-scale research facilities.

The company was founded in February 2015 by Dr. Damian Barre and Prof. Franz X. Kärtner in 2015. The project is financed with almost 130 000 EUR by the Helmholtz Association “Helmholtz Enterprise” program over one year starting in August 2015. The “Ultrafast Optics and X-rays”-Group also grants the same sum of money to the project. This funding includes staff and material costs as well as management support for consultancy in the field of business management, finance, marketing and sales.

The goal of the Helmholtz Enterprise project “HI-PULSE” is to setup the new company and to expand the range of products to include laser sources. The Cycle GmbH will use the Helmholtz funds to bring a patented ultrashort pulse laser into a final product. Finally, the laser will be sold commercially and offered to the scientific community as well as to industry, for example in the field of material processing.
