In many atomic fluorescence applications a non - dispersive optical system may be used.

在许多原子荧光法的应用中，可以采用非分散的光学系统。

We find that dispersive properties inside the micro-cavity lead to frequency shift of the defect modes. The defect modes can be amplified as optical gain is introduced into system.

另外，当通过复介电常数的虚部引入光学增益后，我们发现缺陷模在增益介质中被放大，其阈值特性和缺陷折射率的密切相关。
