The cascade parametric down-conversion of photons in the optical resonator in pulsed regime is considered for production of three-photon states. Photon number distributions, as well as the Wigner functions are investigated for subharmonic mode in qua

Preparation of nonclassical states that are described by negative Wigner functions is studied for an anharmonic oscillator under parametric excitation (AOPE). The over-transient pulsed regime of AOPE driven by a train of Gaussian laser pulses is anal

We consider quantum dynamics of a parametrically driven anharmonic oscillator (PDAO) at a few-photon level. In this scheme the oscillatory mode is excited through the degenerate down-conversion process. This scheme could be experimentally realized in

We study the excitation of nonlinear dissipative oscillator under influence of a monochromatic force at the level of a few quanta. With this purpose we consider an optical parametric oscillator combined with phase-modulation in which the oscillatory

The Fock states are usually generated by using interaction of oscillatory mode with atomic systems driven by a coherent field. We demonstrate that production of Fock states is also realized in the specific operational regimes of a single nonlinear os

It is known that dissipative chaos might satisfy scaling invariance. We discuss this statement from point of view of quantum-classical transition for a model of anharmonic driven dissipative oscillator with time-modulated parameters. We apply the sca
