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…

Anomalous sub-kelvin thermal frequency shifts of ultra narrow-linewidth solid state emitters
X. Lin, M. T. Hartman, B. Pointard +5
We investigate the frequency response of narrow spectral holes in a doped crystal structure as a function of temperature below 1 K. We identify a particular regime in which this re…
