DESY spin-off Cycle: Unique femtosecond fiber lasers

In this episode, we dive into the world of Cycle GmbH, a DESY
spin-off company that was founded in 2015. From scientific
excellence to industrial application, we explore how Cycle is
redefining precision in time synchronization.
 
What does Cycle do?
Cycle develops ultra-stable laser systems that synchronize
optical and radio-frequency systems with femtosecond
precision. Their technology, based on fiber and
ultrashort-pulse lasers, enables groundbreaking accuracy for
applications in research, medical technology, and even
space missions – including collaborations with the
European Space Agency (ESA).

What makes their work innovative?
Cycle bridges the gap between world-class research and
industrial-grade implementation. Their solutions are
critical for facilities and technologies where even the tiniest
timing errors can have massive consequences – from particle
accelerators to satellite systems. By translating cutting-edge
photonics research into scalable products, Cycle is setting new
standards in ultrafast synchronization.

Who’s at the mic?
We’re joined by three key voices behind Cycle’s success:



Prof. Dr. Franz X. Kärtner – Co-founder and
Managing Director of Cycle, professor at the University of
Hamburg and MIT, and a global leader in ultrafast laser
science.


Tim Bode – Early investor and experienced
business angel with a focus on deep tech startups.


Gencer Sahin – Head of Investments at IFB
Innovationsstarter Fonds Hamburg, supporting high-potential
tech ventures in the region.
