Analysis of the boundary conditions’ effect on the features of back-side-coated chirped mirror

摘要: 应用耦合模方程对光波在后端镀膜啁啾反射镜中的传播规律进行分析计算,在分析的过程中加入了边界条件的影响,推导出后端镀膜啁啾反射镜在理想情况下的反射率和穿透深度的解析表达式。分析和计算的结果都表明,考虑了边界条件后,对光波在后端镀膜啁啾反射镜中传输规律的描述更加完整,对后端镀膜啁啾反射镜的主要特性的分析计算更为精确。

Abstract: The analytical expressions of reflectance and penetration depth of a light beam transmitted in the back-side-coated chirped mirror are obtained through couple-mode equations with boundary conditions.The results hows that it is more integrated and precise in calculating and analyzing the light's transmission rule in the BASIC mirror after taking boundary conditions into consideration.
