摘　　要：对六能级原子与2个强激光场和2个弱探测场相互作用产生的交叉克尔效应进行了研究。通过建立相关物理模型推导出系统有效哈密顿量。结果表明,交叉克尔效应随着2个弱探测场的增强而增强。An effective cross-Kerr Hamiltonian is derived for a six-level atom interacting with two strong electromagnetic fields and two weak probes by using time-dependent perturbation theory.When there is the large detuning in the six-level atom and probes,the system is back to the ground state by the spontaneous emission and cross-Kerr nonlinearity increases with two weak probes.

关 键 词：六能级原子系统 有效哈密顿量 交叉克尔效应
