| 摘 要： | 本文讨论了光场与 V 型三能级系统近共振相互作用的半经典模型,由此求出了近共振激发时激发态的粒子数分布及由此产生的激发态受激喇曼散射(ESSRS)的增益,并研究了弛予,光强及失谐等因素对增益的影响,理论得出的结果与在钠原子中观察到的实验结果有较好的一致。

SEMICLASSICAL TREATMENT OF THE EXCITED STATE STIMULATED RAMAN SCATTERING |
| |
| Abstract: | using the semiclassical model ot the near resonant interaction between the optical fields and V-type three level system,we have got the expression of the population distribution of the excited states and the gain of the excited state stimulated Raman scattering(ESSRS).The dependences of the ESSRS gain on the relaxation,incident power densit and the detuning were also investigated. The calculated results were in good agreement with the experimental results from- the sodium atoms. |
