| 中文摘要: |
| 为了确定染料调Q的Nd3+∶YAG激光器发射的单次激光脉冲的偏振性,利用偏振分束立方体和双通道激光能量计,实验测量了激光脉冲经偏振分束后P偏振光和S偏振光的能量比,分析总结了激光器的偏振性。结果表明:激光器偏振性个体差异很大,不存在统一性;每一台激光器都有各自的偏振性,同一台激光器前后发射的激光脉冲的偏振性可能一致,也可能变化较小,也可能完全随机。产生偏振性的具体原因有待进一步研究。 |
| 英文摘要: |
| To define polarized character of dye Q switched Nd3+∶YAG laser of one output laser pulse, polarized beam divider cube and dual channel laser energy meter are used. The energy proportion of P polarized laser burst and S polarized laser burst is measured after polarized beam dividing and the polarized character of laser is analyzed and generalized. The results indicated that a great individual difference is existent and the unitarity can not be found in polarized character of laser. Polarized character of variant laser is different, Polarized character of front to rear laser burst is concordant, or smaller diversity, or completely random. The reason of polarized character will be researched further. |
