- Abstract: We introduce the concept of a squeezed laser, in which a squeezed cavity mode
develops a macroscopic photonic occupation due to stimulated emission. Above
the lasing threshold, the emitted light retains both the spectral purity
inherent of a laser and the photon correlations characteristic of a photonic
mode with squeezed quadratures. Our proposal, which can be implemented in
optical setups, relies on the parametric driving of the cavity and dissipative
stabilization by a broadband squeezed vacuum. The squeezed laser can find
applications that go beyond those of standard lasers thanks to the squeezed
character, such as the direct application in Michelson interferometry beyond
the standard quantum limit, or its use in atomic metrology.

In active imaging protocols, information about a landscape is encoded into the spatial mode of a scattered photon.
We show that backaction in this setting arises from spatial photon shot noise, an effect that cannot be observed in single-mode optomechanics.
In conjunction with high-$Q$ nanomechanics, our findings point to new opportunities at the interface of quantum imaging and optomechanics.

coherent control of the dynamics of an optical tweezer phonon laser is used to share coherence between its different modes of oscillation.
Coherence can be transferred across different modes of an optical tweezer phonon laser, and are a step toward using these systems for precision measurement and quantum information processing.

of the population inversion: transition to lasing in the class-B limit [62.997667081978825]
No class-B quantum density-matrix model is available to date, capable of accurately describing coherence and photon correlations within a unified theory.
Here we carry out a density-matrix theoretical approach for generic class-B lasers, and provide closed equations for the photonic and atomic reduced density matrix in the Fock basis of photons.
This model enables the study of few-photon bifurcations and non-classical photon correlations in class-B laser devices, also leveraging quantum descriptions of coherently coupled nanolaser arrays.

We study single photon emission from an optically driven two-photon Raman transition between the biexciton and the ground state of a quantum dot.
The advantage of this process is that it allows all-optical control of the properties of the emitted single photon with a laser pulse.
We show that laser pulses with non-trivial shapes can be used to maintain excitation conditions for which with increasing pulse intensities the on-demand regime is reached.
