Non Demolition Photon Counting by Electromagnetically Induced Transparency of a four Level Inverted Y-type Atoms
شمارش غیرمخرب فوتون هابا استفاده از شفافیت القایی الکترومغناطیسی یک سیستم چهار ترازه Y معکوس
Abstract


We investigated the Electromagnetically Induced Transparency (EIT) for a four-level Inverted-Y atomic system in interaction with three quantized field (one probe field and two coupling fields) by full quantum model. The absorption curve for probe field indicate the dependency of interval between peaks and their altitude on number of coupling field photons that trapped inside the quantum cavity. In this paper we offer a non-demolition counting method for two kind of photon number's inside the cavity on interaction with an ensemble of four-level Inverted-Y atoms and a quantize probe field by analytical calculation of density matrix equations.
