The possibility of converting coherent light to a squeezed state and to a state with sub-Poissonian photon statistics
Abstract
The paper examines the possibility of suppressing quantum fluctuations of photons in CW laser radiation having a Poissonian or thermal distribution function of photon number. This effect can occur as the result of the attenuation of laser radiation during m-photon absorption in atoms or molecules at transitions from the ground state to a higher level. This process is accompanied by the continuous outflow of entropy from the field during the m-photon absorption and the spontaneous scattering of photons into other spectral and spatial modes due to cascade emission through intermediate levels. It is shown that a value of the photon antibunching effect characterized by Q = -1/2 can be obtained through the absorption of intense radiation at a wavelength of 5787.3 A in a cell with sodium vapor.
