Cavity-immune features in the spectra of superradiant crossover laser pulses
Mikkel Tang, Stefan A. Schäffer, Asbjørn A. Jørgensen +4
Lasing in the bad cavity regime has promising applications in precision metrology due to the reduced sensitivity to cavity noise. Here we investigate the spectral properties and ph…
Lasing on a narrow transition in a cold thermal strontium ensemble
Stefan A. Schäffer, Mikkel Tang, Martin R. Henriksen +3
Highly stable laser sources based on narrow atomic transitions provide a promising platform for direct generation of stable and accurate optical frequencies. Here we investigate a…
Dynamics of bad-cavity enhanced interaction with cold Sr atoms for laser stabilization
Stefan Alaric Schäffer, Bjarke Takashi Røjle Christensen, Martin Romme Henriksen +1
Hybrid systems of cold atoms and optical cavities are promising systems for increasing the stability of laser oscillators used in quantum metrology and atomic clocks. In this paper…
Non-linear Spectroscopy of Sr Atoms in an Optical Cavity for Laser Stabilization
Bjarke T. R. Christensen, Martin R. Henriksen, Stefan A. Schäffer +4
We study the non-linear interaction of a cold sample of strontium-88 atoms coupled to a single mode of a low finesse optical cavity in the so-called bad cavity limit and investigat…
Observation of Motion Dependent Nonlinear Dispersion with Narrow Linewidth Atoms in an Optical Cavity
Philip G. Westergaard, Bjarke T. R. Christensen, David Tieri +5
As an alternative to state-of-the-art laser frequency stabilisation using ultra-stable cavities, it has been proposed to exploit the non-linear effects from coupling of atoms with…
