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.
