Abstract

In this article we have analyzed the squeezing and statistical properties of the light gener- ated by the superposition of second harmonic light and degenerate three level squeezed laser beams We have found that the mean photon number of the superposed light beams to be the sum of the mean photon number of that of the constituent light beams However the photon number variance of the superposed light beams does not happen to be the sum of the photon number variances of the separate light beams On the other hand the quadrature variance of the superposed light beams is the sum of the individual light beams Furthermore we have observed that the degree of squeezing for the superposed light beams is the average of the segregate light beams and the degree of squeezing is approximately 53 95 below the coherent state level Even though we have verified that the superposition of subharmonic and second harmonic light with injected degenerate three-level laser beams hehaves squeez- ing we do not show continuous variable entanglement But the absence of the laser beam in the superposition state give rise entangled photons
