AB  - Entangled state of light is one of the essential quantum resources in quantum 
      information science and technology. Especially, when the fundamental principle 
      experiments have been achieved in labs and the applications of continuous 
      variable quantum information in the real world are considered, it is crucial to 
      design and construct the generation devices of entangled states with high 
      entanglement and compact configuration. We have designed and built an efficient 
      and compact light source of entangled state, which is a non-degenerate optical 
      parametric amplifier (NOPA) with the triple resonance of the pump and two 
      subharmonic modes. A wedged type-II KTP crystal inside the NOPA is used for 
      implementing frequency-down-conversion of the pump field to generate the optical 
      entangled state and achieving the dispersion compensation between the pump and 
      the subharmonic waves. The EPR entangled state of light with quantum correlations 
      of 8.4 dB for both amplitude and phase quadratures are experimentally produced by 
      a single NOPA under the pump power of 75 mW.
