可调谐激光晶体S因子和声子能量的估算

Estimation of the Huang-Rhys S factors and phonon energy in tunable laser crystals

本文采用了一种特别的多模电-声子耦合模型,利用室温光谱数据估算可调谐激光晶体的黄昆-里斯(Huang-Rhys)S因子,并与单模耦合模型的结果作了比较.最后,还讨论了S因子与晶场强度及基质晶体价键特性之间的关系.

A special multi-mode eleotron-phonon coupling model has been used in the estimation of the Huang-Rhys S factors and the phonon energy in Or actived tnnable laser crystals by means of room temperature spectrosoopio data. The results are compared with those of the single mode opproximation by using the same experimental data. Finally, the relationship between the S factors and the crystal field strength and valent characteristics is discussed.
