| 摘 要： | 分析了色散棱镜的特性及其顶角设计问题。讨论了色散棱镜和扩束棱镜在布鲁斯特角入射状态下，可组合使用的形式及单程角色散。提出将色散棱镜与扩束棱镜组合使用，可减少色散棱镜个数而获得更大角色散的方法。并据此设计了两个色散棱镜组，在Ｔｉ∶Ｓ激光器中得到实际使用。

Dispersion Prisms and Their Combination in Tunable Laser Cavity |
| |
| Abstract: | : This article analysed the properties and the top angle design of the dispersion prisms. The single trip angle dispersion and usable combinations were discussed in detail, in the condition of dispersion prism and beam enlarged prsim at Brewster incidence. The article pointed out that the combination of dispersion prism and beam enlarged prism could yield a large angle dispersion and decrease the number of dispersion prisms in the laser cavity. The authors had designed two sets of combination of dispersion prism which had been used in Ti∶sapphire laser. |
