摘要：
We investigate how to prepare spin squeezing state base on four wave mixing. By the bosonization method, we analytically and numerically calculate the spin squeezing parameter. Spin squeezed state can be periodically or always prepared for two different cases. The better squeezing can be achieved by increasing the total number of photons and decreasing the. frequency difference.
