摘要：

Is it possible to number squeeze an already sub-Poissonian electromagnetic field? This work presents a system able to squeeze the sub-Poissonian photon statistics of a beam from the down-conversion luminescence produced in a nonlinear crystal by laser pumping. Parameters are shown to stress the experimental difficulties inherent to the process. Even if this sub-Poissonian proposition for the down-converted light state turns out to be unrealistic, the proposed system is, in principle, a singular tool in noise reduction processes.
