- ItemGENERATION OF HIGHLY SQUEEZED STATES IN A 2-PHOTON MICROMASER(1992) ORSZAG, M; RAMIREZ, R; RETAMAL, JC; ROA, LWe consider a lossless two-photon micromaser with atomic polarization. We find that for particular values of the atomic flight time, the field evolves to a pure state which can be made of a superposition of even-photon-number states or odd-number states. These states approach to a perfectly squeezed state as the upper limit of the "trap" increases.
- ItemGENERATION OF PURE STATES IN A 2-PHOTON MICROMASER - EFFECTS OF FINITE DETUNING AND CAVITY LOSSES(1993) ORSZAG, M; ROA, L; RAMIREZ, RIn this paper, we study the generation of pure states in a two-photon micromaser with finite detuning of the intermediate atomic level. This study was done via the temporal evolution of the discrete master equation. We show that it is possible to generate the ideal squeezed vacuum for a broad range of detunings in a lossless cavity and away from the trapping condition. We also-consider the effect of cavity losses.

- ItemNOISE-REDUCTION, LASING WITHOUT INVERSION, AND PUMP STATISTICS IN COHERENTLY PREPARED LAMBDA QUANTUM-BEAT MEDIA(1992) ORSZAG, M; ZHU, SY; BERGOU, J; SCULLY, MOAmplitude-noise reduction and diminished losses are found in a laser system in which the lower level of the usual two-level atom is replaced by a coherently prepared doublet, i.e., a lambda quantum-beat configuration. The role of atomic coherence between the various levels and regular pumping is investigated. When a portion of the output signal is reflected from a phase-conjugate mirror and reinjected into the laser, the locking phase can be altered and a large phase-noise reduction can be obtained.

- ItemPHOTON STATISTICS IN THE POLARIZATION CEL(1991) ORSZAG, M; RETAMAL, JCIn this work we find the photon statistics for the polarization CEL. The master equation, which couples diagonal and off diagonal matrix elements due to the initial atomic coherence, is solved by using the well known Scully-Lamb ansatz. The possible solutions and stability of the steady state photon number are investigated. Typical bistability behavior is found for a small range of the atomic coherence parameter.

- ItemREDUCTION OF PHOTON-NUMBER FLUCTUATIONS IN 2-PHOTON LASERS(1991) ORSZAG, M; RETAMAL, JCWe analyze the effects of pump statistics on degenerate and nondegenerate two-photon lasers. We find that, although the steady-state mean photon numbers are not affected by pump statistics, there is an interesting reduction in the photon-number fluctuations, both in degenerate and nondegenerate two-photon lasers when the pump statistics is regular (p = 1), as compared to the Poissonian case (p = 0).
- ItemSQUEEZING AND BIFURCATION IN THE PHASE PROBABILITY-DISTRIBUTION IN A 2-PHOTON MICROMASER(1991) ORSZAG, M; ROA, L; RAMIREZ, RWe derive a master equation for the two-photon micromaser with atomic coherence. We find that the presence of the atomic coherence modifies the threshold condition in the two-photon micromaser, and also produces squeezing and bifurcation in the phase probability distribution. The maximum squeezing is of 36% and it happens below threshold.
