Traditional lasers function using resonant cavities, in which the round-trip optical path is equal to an integer multiple of the intracavity wavelengths to constructively enhance the spontaneous emission rate. Taking advantage of the cavity enhancement effect, the narrowest sub-10-mHz-linewidth laser and a 10 −16 -fractional-frequency-stability superradiant active optical clock (AOC) have been achieved. However, a laser with atomic spontaneous radiation being destructively inhibited in an anti…

A steady-state superradiant laser with less than one intracavity photon

TLDR
A Raman superradiant laser source is demonstrated in which spontaneous synchronization of more than one million rubidium-87 atomic dipoles is continuously sustained by less than 0.2 photons on average inside the optical cavity, and isolation of the collective atomic dipole from the environment is demonstrated by cavity frequency pulling measurements.

Active optical frequency standard using sequential coupling of atomic ensembles

Recently, several theoretical proposals addressed the generation of an active optical frequency standard based on atomic ensembles trapped in an optical lattice potential inside an optical resonator.

Realization of phase locking in good-bad-cavity active optical clock.

TLDR
This paper for the first time experimentally realizes the cavity-length stabilization of the 1064/1470 nm DW-AOCs by utilizing the phase locking technique of two independent 1064 nm good-cavity lasers.

Dual-Wavelength Good–Bad-Cavity Laser System for Cavity-Stabilized Active Optical Clock

TLDR
This work proposes a scheme of cavity-stabilized active optical clock, which consists of two key procedures: the good-cavity signal is locked to a reference cavity by the Pound–Drever–Hall (PDH) technique to stabilize the main-Cavity length, and the frequency stability of the bad-c Cavity signal will break this noise floor due to the suppression of the cavity-pulling effect.

Active optical frequency standards using cold atoms: Perspectives and challenges

We consider various approaches to the creation of a high-stability active optical frequency standard, where the atomic ensemble itself produces a highly stable and accurate frequency signal. The

Experimental realization of a one-atom laser in the regime of strong coupling

TLDR
Observations of the second-order intensity correlation function demonstrate that the experimental realization of a one-atom laser operated in the regime of strong coupling generates manifestly quantum (nonclassical) light, typified by photon anti-bunching and sub-poissonian photon statistics.

Pulse Delay Time Statistics in a Superradiant Laser with Calcium Atoms.

TLDR
A superradiant emission of hyperbolic secant shaped pulses into the cavity with an intensity proportional to the square of the atom number, a duration much shorter than the natural lifetime of the ^{3}P_{1} state, and a delay time fluctuating from shot to shot are observed in excellent agreement with theoretical predictions.

Radiative decay and level shift on an atom in an optical resonator

This thesis describes a theoretical and experimental investigation of the intensities, linewidths, and frequencies of radiation by an atom in an optical resonator. It is found that the atom's

We present the first characterization of the spectral properties of superradiant light emitted from the ultra-narrow, 1 mHz linewidth optical clock transition in an ensemble of cold $^{87}$Sr atoms.
