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…
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…
Temperature-dependent mechanical losses of Eu:YSiO for spectral hole burning laser stabilization
Nico Wagner, Johannes Dickmann, Bess Fang +2
We investigate the mechanical loss characteristics of Eu:YSiO$\unicode{x2013}$a promising candidate for ultra-low-noise frequency stabilization through the spectral…
