Query: Pulsed "three-photon" light   Generating multi-photon entangled states is a primary task for applications
of quantum information processing. We investigate production of photon-triplet
in a regime of light amplification in second-order nonlinear media under action
of a pulsed laser beam. For this goal the process of cascaded three-photon
splitting in an optical cavity driven by a sequence of laser pulses with
Gaussian time-dependent envelopes is investigated. Considering production of
photon-triplet for short-time regime and in the cascaded three-wave collinear
configuration Generating multi-photon entangled states is a primary task for
applications of quantum information processing. We investigate production of
photon-triplet in a regime of light amplification in second-order nonlinear
media under action of a pulsed laser beam. For this goal the process of
cascaded three-photon splitting in an optical cavity driven by a sequence of
laser pulses with Gaussian time-dependent envelopes is investigated.
Considering production of photon-triplet for short-time regime and in the
cascaded three-wave collinear configuration we shortly analyze preparation of
polarization-non-product states looking further applications of these results
in the cascaded optical parametric oscillator. It is also demonststed the
nonclassical characteritics of the photon-triplet in phase-space on the base of
the Wigner function. Calculating the normalized third-order correlation
functions below-and at the generation threshold of cascaded optical parametric
oscillator, we demonstrate that in the pulsed regime, depending on the duration
of pulses and the time-interval separations between them, the degree of
three-photon-number correlation essentially exceed the analogous one for the
case of continuous pumping.
