Non-synchronous effect on the squeezed light generated by parametric amplification

摘要

We solved the motion of (a-circumflex - a-circumflex) in the optical parametric amplification process keeping non-synchronous terms. The equation can be written as a Mathieu equation form. Solving this equation, we found the effect of non-synchronous terms on the amplitude of the generated parametric oscillation beam. The quantum fluctuations of the signal beam were also affected, and so was the value of the pump-signal phase difference that produces minimum uncertainty squeezing.
