主　　题：four-wave mixing phase matching frequency degenerate and spatial nondegenerate metrology 

摘      要：We theoretically investigate the frequency-nondegenerate and frequency degenerate squeezed lights with a four-wave mixing process(4WM)driven by two pump fields crossing at a small *** from a 4WM process driven by a single pump field,the refractive index of the corresponding probe field,np,can be converted to a value that is greater than 1 or less than 1 by an angle *** the new region with np1,the bandwidth of the gain is relatively large due to the slow change in the refractive index with the two-photon *** this region with an exchange of the roles of the pump and probe beams,the frequency degenerate and spatial nondegenerate twin beams can be generated,which has potential application in quantum information and quantum metrology.
