摘要

We introduce a two-dimensional Bose-Einstein condensation model consisting of massive photon and photon-pair.Based on the new nonlinear model,the traditional process of second harmonics generation is reinvestigated.In order to describe the process,a new quantum phase,the harmonic phase,is introduced.The order parameter of the new physical phase is also given in this paper.
