摘要：

The process of three-photon down-conversion 3 omega --> omega + omega + omega in an optical cavity is analyzed theoretically. A classical feature uf this system is a first-order transition of the fundamental mode above a threshold 3 omega pump power. We calculate the properties of the intra-and extracavity states using analytical calculations and quantum trajectory simulations. A positive, non-Gaussian Wigner function exhibiting a threefold symmetric is found. Above threshold the Wigner function displays separate peaks among which tunneling occurs.
