| 摘 要： | 假设介质是中心对称的,并考虑入射场与感应场同介质相互作用,在经典力学框架内,把介质的运动方程化为双频激励下的Duffing方程,用多尺度法揭示了拉曼谱的复杂结构。分析了系统的倍频共振和组合共振。结果表明,在拉曼线两侧出现了很多伴线,而且这些伴线的强度是彼此不同的;指出了可以利用共振效应,通过适当的参数选择或介质选择就可获得强的激光输出。

| Abstract: | By supposing the medium to be center symmetric and considering the interaction of incident field and induced field with the medium,the complex spectral construction of Raman spectrum was revealed with multi-scalar techniques by reducing the motion equation to Duffing equation under bi-frequency exitation in the classical mechanics frame.The times frequency resonance and the combination resonance were analyzed and the resuts showed that many satellite lines appeared at the both sides of Raman line,and the in... |
