| 摘 要： | 从膜层内的驻波场分布和对膜系的相移要求出发，利用倍频的设计思想对氧碘激光腔内45°入射高反射镜进行优化设计，得出了满足对632.8nm和1 315nm双波长高反射，同时在1 315nm处有180°位相延迟的新膜系结构，与传统的设计膜系相比，此膜系大大降低了高折射率层的厚度，薄膜性能有望得到进一步提高。

| Abstract: | From the electric field distribution and the phase shift requirement for the film, the mirror coating in COIL resonator at 45 deg incidence angle is designed using multiple frequency design method. A new high reflection design at two wavelengths (632.8nm and 1315nm) is attained with 180 deg phase retard at 1315nm. Compared with the conventional design, the thickness of high refractive index material of the new design is reduced largely. Hopefully, the performance of the mirror can be improved greatly. |
