Quantum Trajectory Analysis of the Two-Mode Three-Level Atom Microlaser
, 2011 We consider a single atom laser (microlaser) operating on three-level atoms interacting with a two-mode cavity. The quantum statistical properties of the cavity field at steady state are investigated by the quantum trajectory method which is a Monte ...

Controlling the gain contribution of background emitters in few-quantum-dot microlasers
New Journal of Physics, 2018 We provide experimental and theoretical insight into single-emitter lasing effects in a quantum dot (QD)-microlaser under controlled variation of background gain provided by off-resonant discrete gain centers.

Observation of sub-Poisson photon statistics in the cavity-QED microlaser
, 2005 We have measured the second-order correlation function of the cavity-QED microlaser output and observed a transition from photon bunching to antibunching with increasing average number of intracavity atoms.

Gold nanorod plasmonic upconversion microlaser [PDF]
14th IEEE International Conference on Nanotechnology, 2013 Plasmonic-photonic interactions have stimulated significant interdisciplinary interest, leading to rapid innovations in solar design and biosensors. However, the development of an optically pumped plasmonic laser has failed to keep pace due to the difficulty of integrating a plasmonic gain material with a suitable pump source.

Automatic detection of spermatozoa for laser capture microdissection [PDF]
, 2008 In sexual assault crimes, differential extraction of spermatozoa from vaginal swab smears is often ineffective, especially when only a few spermatozoa are present in an overwhelming amount of epithelial cells.

Macroscopic Interference Effects in Resonant Cavities [PDF]
, 1999 We investigate the possibility of interference effects induced by macroscopic quantum-mechanical superpositions of almost othogonal coherent states - a Schroedinger cats state - in a resonant microcavity.
