Twin-beams Statistics for Strong Pumping

چکیده
Twin beams generated by cw optical parametric oscil lators (OPO) show intensity difference quantum noise reduction below the shot-noise level (SNL) as predicted by Reynaud et al. [1] and proved experimentally in dif ferent configurations [2], At powers higher than four times the threshold also the single beam intensity noise should reduce below SNL in some frequency range [3], an effect competing with relaxation oscillations [4]. In this paper we report a study of correlations spectra in two bulk a-cut KTP triply resonant OPOs.

Quantum correlated twin atomic beams via photodissociation of a molecular Bose-Einstein condensate
The successful production of Bose-Einstein condensates ~BEC! has led to measurements indicating that BECs have coherence properties similar to lasers. This suggests that the next stage in obtaining precision measurements in atom optics is the production of atom beams with sub-Poissonian atom statistics—as has been widely demonstrated in photonics applications. Indeed, there is already some indi...
متن کاملTwin beams, nonlinearity, and walk-off in optical parametric oscillators
We study the quantum properties of the spatially tilted macroscopic signal beams in the transverse pattern formed in a degenerate optical parametric oscillator above threshold. We show that walk-off leads to an imbalance in the intensities and fluctuations of these beams when nonlinear multimode interactions are effective. Still, quantum correlations between the two beams are preserved, so that...
متن کامل1D microcavity–based optical parametric oscillator: generation of balanced twin beams in strong and weak coupling regime
We report on a detailed experimental investigation of interbranch parametric scattering processes in onedimensional semiconductor microcavities. Band dispersion and corresponding far field emission patterns are studied by polarization resolved and power dependence measurements under resonant and non-resonant excitation at normal incidence. We demonstrate the realization of optical parametric os...
متن کاملGeneration of squeezed states and twin beams via non-degenerate four-wave mixing in a L system
We show that non-degenerate four-wave mixing in a L system yields strong suppression of quantum phase noise when the probe and conjugate beams are monitored via balanced homodyne detection. Unlike previous calculations performed on similar system, we include situations where the pump beams become resonant with the corresponding two-level transitions. As a result, we find conditions wherein stro...
متن کاملDouble phase-conjugate mirror: convection and diffraction
Development of scattered radiation in the geometry of a double phase-conjugate mirror is investigated numerically in the framework of a two-dimensional model that accounts for both diffraction and noncollinearity of the interacting beams. The large-scale structure of the scattered beams is found to be distorted because of the convective flow of energy out of the interaction region. We show that...
