| 摘 要： | 利用菲涅尔公式分析了Zig—Zag板条中全反射退偏对谐振光束的影响和能量损耗。分析了当谐振光偏振方向与Zig-Zag板条的选偏方向存在偏差时，线偏光经过板条后的偏振态，并计算了各因素对Zig—Zag板条全反射退偏损耗的影响。根据板条全反面的镀膜特点设计合理的谐振光全反射次数可有效地降低Zig—Zag板条的全反射退偏损耗。

| Abstract: | The influence and energy loss of depolarization caused by total internal reflection in Zig-Zag laser slab were ana- lyzed based on Fresnel formulas. If the polarization direction of resonant light and Zig-Zag laser slab are different, the polari- zation state will change when the light through Zig-Zag laser slab. The influence of various factors on the energy loss of de- polarization caused by total internal reflection was calculated. A suitable number of total internal reflection can be calculated according the characters of coating film on the Zig-Zag laser slab, and which can reduce the energy loss of depolarization caused by total internal reflection. |
