Cordierite-based optical resonators with extremely low thermal expansion
Nico Wagner, Thomas Legero, Stefanie Kroker
Applications for ultra-stable lasers outside controlled laboratory environments require compact and robust optical resonators with reduced sensitivity to temperature fluctuations.…
Mechanical loss and stability analysis of NEXCERA in ultra-stable optical cavities
Nico Wagner, Mateusz Narożnik, Marcin Bober +3
NEXCERA has emerged as a ceramic-based material for spacers in ultra-stable optical cavities, with a coefficient of thermal expansion that crosses zero near room temperature. In su…
Thermal-noise Limits to the Frequency Stability of Burned Spectral Holes
M T Hartman, N Wagner, S Seidelin +1
Techniques in frequency stabilization of lasers to fixed-spacer optical cavities have advanced to the point where the ultimate frequency stabilities are limited by thermal noise in…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
Guidelines for designs for ultrastable laser with fractional frequency instability
Joannès Barbarat, Erik Benkler, Marcin Bober +46
Lasers with long coherence time and narrow linewidth are an essential tool for quantum sensors and clocks. Ultrastable cavities and laser systems are now commercially available wit…
