Generation of High-Order Squeezing in Multiphoton Micromaser

Fuli Li, Qing Huang

Published Jan 1, 1996• 0 citations

Abstract

The generation of steady state higher-order squeezing in the sense of Hong and Mandel and also of Hillery in a multiphoton micromaser is studied. The results show that the cotangent state which is generated by the coherent trapping scheme in a multiphoton micromaser can exhibit not only second-order squeezing but also fourth-order and squared field amplitude squeezings. The influence of the cavity loss on the squeezings is investigated.

Generation of higher-order squeezing in a micromaser

Fuli Li, D. L. Lin

The fourth-order squeezing and amplitude-squared squeezing of cotangent states produced in one-atom micromasers are investigated. It is found that optimal squeezing in the cotangent state can be achieved by properly choosing the relative amplitudes of the atomic coherent state. From our study of the dynamic process of the generation of steady-state fourth-order squeezing and amplitude-squared squeezing in one-atom micromasers, it is also shown that for sufficiently large atomic flux, the cavity loss, and finite temperature in the cavity have very little influence on the generation of these higher-order squeezings in practice.

INFLUENCE OF CAVITY LOSS ON GENERATION OF STEADY STATE FOURTH-ORDER AND SQUARED AMPLITUDE SQUEEZING IN MICROMASER

Li Fu-Li, 西安交通大学应用物理系,西安710049

The generation of the steady state fourth-order squeezing and squared amplitude squeezing in a micromaser by the coherent trapping approach is investigated. The results show that if two-level atoms injected into the cavity are initially in coherent state and the flight time of the atoms inside the cavity satisfies the trapping condition, the field can evolve into a coherent trapping state which exhibits steady state fourth-order squeezing and squared amplitude squeezing in the cavity as long as the flux of the atoms is moderately large.

Fourth-order squeezing in the multiphoton Jaynes-Cummings model

Fam Le Kien, M. Kozierowski, Tran Quang

Hong and Mandel's concept of higher-order squeezing [Phys. Rev. Lett. 54, 323 (1985); Phys. Rev. A 32, 974 (1985)] is applied to the generalized multiphoton Jaynes-Cummings model of a single two-level atom interacting with an initially coherent cavity-field mode. The fourth-order squeezing is examined. The field is shown to be intrinsically squeezed to this order for the photon multiple m\ensuremath{\ge}4.

Squeezing and higher-order squeezing in one- and two-photon Jaynes-Cummings models

Christopher C. Gerry, Patrick J. Moyer

We consider the squeezing of the electromagnetic field resulting form the interaction of light in a coherent state with one- and two-photon Jaynes-Cummings models of the two-level atom. We also consider high-order squeezing in the sense of Hong and Mandel [Phys. Rev. Lett. 54, 323 (1985)] and also of Hillery [Phys. Rev. A 36, 3796 (1987)].

Generation of higher-order atomic dipole squeezing in a high-Q micromaser cavity. (VIII). Multi-photon interaction

Rui‐Hua Xie, Qin Rao

In our preceding serial works, we have investigated the generation of higher-order atomic dipole squeezing (HOADS) in a high-Q micromaser cavity, discussing the effects of dynamic Stark shift, atomic damping, atomic coherence and nonlinear one-photon processes and different initial states (for example, correlated and uncorrelated states, superposition states, squeezed vacuum). In this paper, we continue to study HOADS in a high-Q micromaser cavity, but consider that the atom interacts with the optical field via a multi-photon transition process and that the initial atom is arbitrarily prepared. For a vacuum initial field, we demonstrate that HOADS cannot occur if the atom is initially prepared in a chaotic state and that a coherent atomic state generates less efficient and stable HOADS than an arbitrary one. It is found that large detuning may lead to enhanced and strong HOADS.

Squeezing and higher-order squeezing in the three-level, two-mode system

M. H. Mahran

We consider squeezing of the electromagnetic field resulting from the interaction of the three-level ssV-shaped atom with two modes initially taken in coherent-state representation. We also consider higher-order squeezing in the sense of Hong and Mandel [Phys. Rev. Lett. 54, 323 (1985)] and then in the sense of Hillery [Phys. Rev. A 36, 3796 (1987)]. We calculate the two-mode squeezing proposed in [J. Mod. Opt. 34, 709 (1987)] and the sum squeezing defined by Hillery [Phys. Rev. A 40, 3147 (1989)] for an atom starting initially at its ground state.
