Three-photon squeezing: exploding solutions and possible experiments

In the frame of quantum optics the properties of a parametric amplifier of the third subharmonic, described by the Hamiltonian H 3 = iκ(a +3−a 3) 3 , are considered. The average output energy turns into infinity (explodes) at certain critical values of para meters even in the absence of feedback. Th...

Description
Summary:In the frame of quantum optics the properties of a parametric amplifier of the third subharmonic, described by the Hamiltonian H 3 = iκ(a +3−a 3) 3 , are considered. The average output energy turns into infinity (explodes) at certain critical values of para meters even in the absence of feedback. The photon number distribution stays smooth at the explosion moment. The processes of squeezing of the quantum noise and of the photon bunching are discussed. The value of the parameter κ is estimated for a travelling wave amplifier.
