Abstract :
A generalized two-liquid model is used to analyze theoretically the parametric amplifier effects in high-Tc superconducting thin films at the irradiation of the latter by an optical radiation modulated by the intensity. The expressions of the components of surface impedance parameters-dependencies are obtained, the condition of parametric "pump" is simulated, and the gain in power is calculated. The possibility of the creation of the parametric regeneration on the modulation frequency of the surface impedance of a HTSC films is offered.
