摘要
本文采用均匀加宽的四能级原子模型与光泵双光子激光相互作用,其系统具有双光子损耗机制。利用全量子理论推导各原子算符的朗之万方程,进而研究了稳态光子数、频率、线宽及激光运转过程。
In this paper, the model which consists of homogenous broadened four-levelatom is proposed. The two photon laser by optical pumping, which two-photonlosses, is studied by means of the Langevinian theory. The steady-state averagephoton number, the frequency pulling, the linewidth and laser gain processesare obtained.
