Dependence of the squeezing and anti-squeezing factors of bright squeezed light on the seed beam power and pump beam noise



Dependence of the squeezing and anti-squeezing factors of bright squeezed light on the seed beam power and pump beam noise



Optics Letters 44(7): 1789-1792



We demonstrate the dependence of the squeezing and anti-squeezing factors on the seed beam power at different pump beam noise levels. The results indicate that a seed field injected into the optical parametric amplifier (OPA) dramatically degenerates the squeezing factor due to noise coupling between the pump and seed fields, even if both the pump and seed fields reach the shot noise limit. The squeezing and anti-squeezing factors are immune to the pump beam noise due to no noise coupling when the system operates for the generation of squeezed vacuum states. The squeezing factor degrades gradually as the pump beam intensity noise and seed beam power is increased. The influence of the two orthogonal quadrature variations is mutually independent of each other.
