【摘要】 本文探讨了表面二次谐波的增强效应与活性媒质层厚度之间的关联,用实验方法证实了最大的增强效应对应于表面等离子振荡极化激元(Surface Plasmon Polariton)在最佳媒质层厚度条件下的激发,从而与所产生的较高表面场强有关.更多还原

【Abstract】 The correlation between the thickness of the active medium with the enhancement of the second harmonic generation signals on surface is studied. It is identified by experimental method that the maximum enhancement of the second harmonic signal corresponds to the optimum thickness of the active medium where in fact that surface plasmon polariton has been well excited and honce closely related to the strong enrichment of the field generated at the surface.更多还原
