Broadband birefringence spectroscopy with sub-kHz precision
Maximilian Prinz, Dominik Charczun, Marcin Bober +5
Although current amorphous high-reflective mirror coatings have had tremendous success in metrology applications, they are inherently limited by thermal fluctuations in their coati…
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…
Cavity-enhanced spectroscopy in the deep cryogenic regime -- new hydrogen technologies for quantum sensing
Kamil Stankiewicz, Marcin Makowski, MichaÅ SÅowiÅski +13
Spectrometers based on high-finesse optical cavities have proven to be powerful tools for applied and fundamental studies. Extending this technology to the deep cryogenic regime is…
