It is shown that fluctuations of the pumping rate in generation of squeezed states of an electromagnetic field by parametric decay and four-wave scattering are responsible for the finite squeezing limit.

We present a study of the generation of squeezed states through nonlinear three-wave mixing in media with an intensity-dependent index of refraction. In the semiclassical model, perfect squeezing for combination modes can be generated. Using the Fokker-Planck equation approach, the effects of pump (including squeezed pump) and loss are discussed. It is shown that the fluctuations of the pump place no fundamental limit to the degree of squeezing obtainable but losses do give an absolute limit.
