NEW WAY OF STUDY RYDBERG-ATOM
Rydberg原子研究的新方法

It is studied non-degenerate four-wave mixing on the Rydberg-atom.The Rydberg-atom′s research are important at high stimulated in the atomic physics.We first use non-degenerate four-wave mixing in the Rydberg-atom system and study one of the FWM spectrums which is collided broaden under different pressures.NDFWM is a non-linear optical method，and the signal light is a coherent light，which has high explore sensibility and has good advatage of traditionally Rydberg-atom research methods.
