Non-Gaussian states produced by close-to-threshold optical parametric oscillators: role of classical and quantum fluctuations / V. D'Auria, C. de Lisio, A. Porzio, S. Solimeno, J. Anwar, M. Paris. - In: PHYSICAL REVIEW A. - ISSN 1050-2947. - 81:3(2010), pp. 033846.033846.1-033846.033846.9.
Abstract:
Quantum states with non-Gaussian statistics generated by optical parametric oscillators (OPO) with fluctuating
parameters are studied by means of the kurtosis excess of the external field quadratures. The field generated is
viewed as the response of a nonlinear device to the fluctuations of pump laser amplitude and frequency, crystal
temperature, and cavity detuning, in addition to quantum noise sources. The kurtosis excess has been evaluated
perturbatively up to the third order in the strength of the crystal nonlinear coupling factor and the second order
in the classical fluctuating parameters. Applied to the device described in Opt. Expr. 13, 948 (2005), the model
has given values of the kurtosis excess in good agreement with the measured ones.
