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…

First-order thermal insensitivity of the frequency of a narrow spectral hole in a crystal
S. Zhang, S. Seidelin, R. Le Targat +3
The possibility of generating an narrow spectral hole in a rare-earth doped crystal opens the gateway to a variety of applications, one of which is the realization of an ultrastabl…
