这些转变都对光学增益有贡献。
从激光探测告警光学系统的视场和光学增益出发，分析了浸没透镜的光学增益和像差特性。
The optical gain and aberration characteristics of immersion lens are analyzed based on FOV and optical gain of optical systems used in laser warning device.
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。
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.
