In contrast to stabilization against a reference cavity, which is the approach currently used for the most highly stabilized lasers, stabilization against an atomic transition does not suffer from Brownian thermal noise. Spectroscopy of ultranarrow optical transitions in a cavity operates in a very highly saturated regime in which nonlinear effects such as bistability play an important…

Laser stabilization using saturated absorption in a cavity QED system

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 millikelvin

Prospects for frequency stabilization using collective effects of strontium atoms in an optical cavity

The stability of current state-of-the-art optical atomic clocks is mostly limited by the frequency noise of the interrogation oscillator through the Dick effect. To achieve the heralded ultimate

Nonlinear spectroscopy of Sr atoms in an optical cavity for laser stabilization

We study the nonlinear interaction of a cold sample of 88 Sr atoms coupled to a single mode of a low finesse optical cavity in the so-called bad cavity limit, and we investigate the implications for

Magnetically Induced Optical Transparency on a Forbidden Transition in Strontium for Cavity-Enhanced Spectroscopy.

A narrow spectroscopic feature approaches the atomic transition linewidth, which is much narrower than the cavity linowidth, and is highly immune to the reference cavity length fluctuations that limit current state-of-the-art laser frequency stability.

The concept of an active optical frequency standard was proposed about 10 years ago. The idea was to use optically trapped alkaline-earth atoms as a gain medium to built an extremely narrow-line

Towards passive and active laser stabilization using cavity-enhanced atomic interaction

Ultra stable frequency references such as the ones used in optical atomic clocks and for quantum metrology may be obtained by stabilizing a laser to an optical cavity that is stable over time.

Magnetically induced optical transparency with an ultranarrow spectrum

Magnetically induced optical transparency (MIOT) is a technique to realize the narrow transmission spectrum in a cavity quantum electric dynamics (cavity QED) system, which is demonstrated in the

Phase diagram for injection locking a superradiant laser

We study experimentally and theoretically the response of a superradiant or bad-cavity laser to an applied coherent drive. We observe two forms of synchronization (injection locking) between the

Laser stabilization on velocity dependent nonlinear dispersion of Sr atoms in an optical cavity

The development of simple and reliable high stability clock lasers is of great importance for future state-of-the-art optical clocks [1]-[5] and for future transportable optical clocks [6], [7].

An active optical frequency reference using a pulsed superradiant laser

We will describe a next-generation active atomic frequency reference based on super-radiant pulses of laser light from the ultra-narrow, 1 mHz linewidth, optical clock transition in an ensemble of
