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…
Laser stabilization using saturated absorption in a cavity QED system
D. A. Tieri, J. Cooper, Bjarke T. R. Christensen +2
We consider the phase stability of a local oscillator (or laser) locked to a cavity QED system comprised of atoms with an ultra-narrow optical transition. The atoms are cooled to m…
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…
