Various aspects of the phase dynamics of an atom-laser scheme based on binary collisions are investigated. Analytical estimates of the influence of elastic atom-atom collisions on the laser linewidth are given, and linewidths achievable in a recently proposed atom-laser scheme [M. G. Moore and P. Meystre, Phys. Rev. A 56, 2989 (1997)] are evaluated explicitly. The extent to which a relative phase can be established between two interfering atom lasers as well as the properties of this phase are also investigated.Various aspects of the phase dynamics of an atom-laser scheme based on binary collisions are investigated.

Model of the atom laser with Raman outcoupling

Chasib A. Emshary, Shaker I. Esa, Arafat J. Almanea

In the present paper, the authors start from the interaction of a system of two-level atoms with an electromagnetic field to drive the interaction Hamiltonian between these two-level atoms. Second, introduce the equations of motion which describing the dynamics of atom laser depending on the interaction Hamiltonian, this interaction Hamiltonian will be used to describe the outcoupling process in a Raman atom laser. Also, the authors model the dynamics of an atom laser produced by outcoupling three-level atoms from a Bose-Einstein condensate (BEC) via a Raman transition and investigate the transfer of quantum statistics from one of the optical modes to the atomic field. Finally, the authors mathematical treatment leads to the same as equations appears in literature which allowed obtaining the dynamics for any atom laser systems.In the present paper, the authors start from the interaction of a system of two-level atoms with an electromagnetic field to drive the interaction Hamiltonian between these two-level atoms.

Dynamics of bad-cavity-enhanced interaction with cold Sr atoms for laser stabilization

Stefan Alaric Schäffer, Bjarke T. R. Christensen, Martin R. Henriksen +1 more

Hybrid systems of cold atoms and optical cavities are promising systems for increasing the stability of laser oscillators used in quantum metrology and atomic clocks. In this paper we map out the atom-cavity dynamics in such a system and demonstrate limitations as well as robustness of the approach. We investigate the phase response of an ensemble of cold $^{88}\mathrm{Sr}$ atoms inside an optical cavity for use as an error signal in laser frequency stabilization. With this system we realize a regime where the high atomic phase shift limits the dynamical locking range. The limitation is caused by the cavity transfer function relating input field to output field. The cavity dynamics is shown to have only little influence on the prospects for laser stabilization, making the system robust towards cavity fluctuations and ideal for the improvement of future narrow linewidth lasers.Hybrid systems of cold atoms and optical cavities are promising systems for increasing the stability of laser oscillators used in quantum metrology and atomic clocks.
