  We report the experimental demonstration of polarization squeezed beam at 795
nm by combining a quadrature squeezed beam with a coherent beam. The quadrature
squeezed beam is generated by a degenerate optical parametric amplifier based
on a PPKTP crystal. Stokes parameter squeezing of -3.8 dB and anti squeezing of
+5.0 dB is observed. This polarization squeezed beam resonant to rubidium D1
line has potential applications in quantum information networks and precise
measurement beyond the shot noise limit.
