Abstract

The work is devoted to applications of group-theoretic coherent states to
describe the nonlinear optical effects. Important in modern quantum information
process of parametric down conversion is studied. It is shown that the use
of superpositions of coherent states of SU(1; 1) allows to increase the squeezing
of generated photon pairs.
