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…
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…
Precision measurements of electric-field-induced frequency displacements of an ultranarrow optical transition in ions in a solid
S. Zhang, N. Lučić, N. Galland +5
We report a series of measurements of the effect of an electric field on the frequency of the ultranarrow linewidth optical transition of …
Position- and momentum-squeezed quantum states in micro-scale mechanical resonators
Y. Le Coq, K. Mølmer, S. Seidelin
A challenge of modern physics is to investigate the quantum behavior of a bulk material object, for instance a mechanical oscillator. We have earlier demonstrated that by coupling…
High-precision methanol spectroscopy with a widely tunable SI-traceable frequency-comb-based mid-infrared QCL
R. Santagata, D. Tran, B. Argence +14
There is an increasing demand for precise molecular spectroscopy, in particular in the mid-infrared fingerprint window that hosts a considerable number of vibrational signatures, w…
Rapid cooling of a strain-coupled oscillator by optical phaseshift measurement
Signe Seidelin, Yann Le Coq, Klaus Mølmer
We consider an optical probe that interacts with an ensemble of rare earth ions doping a materialin the shape of a cantilever. By optical spectral hole burning, the inhomogeneously…
