From Heat Capacity to Coherence in Ultra-Narrow-Linewidth Solid-State Optical Emitters at Sub-Kelvin Temperatures
D Serrano, T Klein, C Marcenat +5
The coherence properties of optical emitters in crystals are crucial for quantum technologies and optical frequency metrology. Cooling to sub-kelvin temperatures can markedly enhan…

Homogeneous Linewidth Behaviour of Narrow Optical Emitters at Sub-kelvin Temperatures
X Lin, M T Hartman, P Goldner +3
We explore the properties of ultra-narrow spectral holes in ensembles of solid-state emitters in crystals over a range of sub-kelvin temperatures, with a focus on their potential a…
