AB  - The non-measurement based coherent feedback control (CFC) is a control method 
      without introducing any backaction noise into the controlled system, thus is 
      specially suitable to manipulate various quantum optical systems for preparing 
      nonclassical states of light. By simply tuning the transmissivity of an optical 
      controller in a CFC loop attached to a non-degenerate optical parametric 
      amplifier (NOPA), the quantum entanglement degree of the output optical entangled 
      state of the system is improved. At the same time, the threshold pump power of 
      the NOPA is reduced also. The experimental results are in reasonable agreement 
      with the theoretical expectation.
