(19971001)We present a semiconductor laser model which incorporates the gain bandwidth and nonlinear gain by using the multiband microscopic theory of an electron  hole plasma in a semiconductor quantumwell medium. The approach ...

(19980201)On the basis of the Jones vectors and matrices formalism a mathematical model has been developed of a singlelongitudinalmode (fourfrequency) ring gas laser with an arbitrary type of cavity anisotropy and with the ...

(19970601)It is shown that, departing from Dirac's intensity  phase commutator, a Hermitian operator can be found, conjugate to the number operator, N. We also show that this operator is equivalent to that given by Turski.

(19951001)The properties of amplitude Nthpower squeezing (ANPS) of a field in the JaynesCummings model for the initial atom being in the ground state and the radiation field being in a coherent state are investigated. It is found ...

(19951201)The amplitude squeezing of coherent light in a highQ cavity by interaction with atoms entering regularly one by one is studied. The interaction is assumed to be of twophoton transition type, and the mean photon number N ...

(19980601)A very simple analytical expression of cutoff wavenumbers for TM waves in a nonlinear MQW slab waveguide with Kerrlike nonlinearity is presented for the first time using a perturbation technique.

(19960201)We use a quantumtrajectory based method (a generalization of earlier work by Mollow) to derive results for the population inversion and atomic dipole of a single atom interacting with a cavity field which is allowed to ...

(19960601)An atom laser is a device which would ideally produce a coherent excitation of a single mode of the Boseatom field. That is to say, an atom laser field would have a well defined number of atoms, and a slow rate of phase ...

(19960601)We study experimentally quantum effects in atomic motion for a classically chaotic regime. A standing wave is pulsed on periodically in time, and the resulting atomic momentum is measured. Momentum grows diffusively until ...

(19960601)We propose a model for globally coupled lasers with intracavity second harmonic generation in which each laser gain is modulated separately. Suitable selection of the modulation phases can shift the resonance expected at ...

(19950401)We analyse the problem of intracavity second harmonic generation to determine properties of the antiphased states that have been observed in this system. We study the timeperiodic solutions by means of a perturbation ...

(19960201)We determine numerically the response of a multimode laser with intracavity secondharmonic generation to a periodic modulation of the gain in the linear and nonlinear regimes. We show that resonances can appear either at ...

(19950401)The unitary operator representing the action of a linear lossless passive beam splitter is presented. The derivation is based on an elementary grouptheoretical approach that allows us to understand this action in terms ...

(19960201)In this paper results are reported for the application of the quantum trajectory method to analysing the dynamics of the micromaser. The master equation for the cavity field is derived by a method which highlights the close ...

(19970201)We study the interaction of a quantized singlemode standingwave cavity field with a twolevel atom de Broglie wave. For the sake of simplicity we consider the field to be far detuned and the atom to be moving in the Raman ...

(19981001)A scheme is proposed for the generation of superpositions of multimode coherent states, i.e. multimode Schrödinger cat states. In the scheme a type threelevel atom is sent through many cavities filled with coherent ...

(19960201)We give an explicit stochastic Hamiltonian model of discontinuous unitary evolution for quantum spontaneous jumps like in a system of atoms in quantum optics, or in a system of quantum particles that interacts singularly ...

(19960601)We describe a simple and robust method of creating an efficient largeangle adiabatic passage beamsplitter that does not require the light fields to be pulsed. We present simulations that show momentum splittings of , where ...

(19980601)We propose a new atomic beamsplitter which uses Raman transitions via the far detuned excited state of an atom induced by four standing light waves. The splitting is not restricted to the RamanNath regime, and spontaneous ...

(19950601)The authors demonstrate the effect of atomic coherence on the generic example of two lossless micromasers coupled in series by a common pump beam of excited twolevel atoms. The fields are studied via conditional measurements ...
