Next generation ultrastable lasers: reducing thermal noise limit and overcoming technical limitations with new materials and technologies

Project: EU project

Project Details


Ultrastable lasers for optical clocks, science and technology

Ultrastable lasers are basic building blocks of optical clocks and benefit navigation, telecommunications, and synchronization of large-scale experimental facilities. New technologies promise substantial reduction of their current frequency stability.

Project addresses all the current limitations of ultrastable lasers, aiming for next generation of these devices with instabilities at and below 110–17.

VTT MIKES develops methods for active vibration control and thermal noise suppression in Fabry-Perot cavities and implements different approaches for phase-locked loops to improve the
signal-to-noise ratio of optical beatnotes.
