Abstract:

The noise properties of non-degenerate parametric amplifiers with
absorption losses which are different for the two beams are analysed by means of a
semiclassical approach which enables the direct derivation of the Langevin
equations for the optical fields from the quantum Heisenberg equations . Several
statistical quantities are calculated and the implications of the present results for
sub shot-noise absorption measurements are discussed finally .
