频率牵引
In this paper, the model which consists of homogeneous broadened three atomic level is proposed, when both the pump classical field and laser field exist we discuss the gain, frequency pulling and threshold condition of the weak pumping.
本文给出一均匀增宽的三能级原子模型,在泵浦场和激光场同时存在时,讨论了双光子激光的增益、频率位移及弱泵浦时,稳态运转的阈值条件。
