Femtosecond parametric excitation of electromagnetic fteld in a cavity
Lozovik Yu.E., Tsvetus V.G., Vinogradov E.A.
We discuss the method of parametric excitation of electromagnetic waves in a cavity (particularly from vacuum state) by creating of dense plasma layer which represents the "mobile" wall of the cavity. The mobue plasma layer may be produced by the irradiation of semiconductor film with femtosecond laser pulse. Parametrically excited radiation may be resolved from radiation of another origin by analysis of it's squeezing, specific angle distribution and by time resolved registration.
