  1. Reflection and refraction of a plane wave at the interface of double negative and double positive media

    平面波在雙負和雙正參數媒質界面的反射與折射
  2. The initial or frozen-in double refraction is replaced by an equivalent or virtual state of stress.

    初雙折射或被凍結的雙折射,可用一個等效或有效應力狀態來代替。
  3. We analyze the generation of external cavity frequency - doubling with knbo3 crystal theoretically. in order to get the second - order nonlinear conversion from 858nm to 429nm with knbo3, we use non - critical type - i phase - matching to avoid the walk - off effect the corresponding optimum focusing condition is as followings : double refraction parameter b = 0, focus parameter = 2. 84, optimum phase mismatch parameter = 0. 574. based on the theoretical analysis and numerical calculations, we obtain the ideal nonlinear conversion coefficient about 1. 45 % / w with crystal length of 7mm and 2. 07 % / w with crystal length of 10mm at the phase - matching temperature around 23. 50c

    根據對其倍頻原理及性能的分析討論,在用該晶體完成波長從858nm到429nm的二階非線性轉換時,採用非臨界相位匹配條件(此時無離散效應,對應的雙折射參數b = 0 ,共焦長度為= 2 . 84 ,最佳相位失配因子為= 0 . 574 ) ,在相位匹配溫度約為23 . 5時,理論上通過計算得到理想情況下非線性轉換系數約為1 . 45 / w (長度為7mm ) , 2 . 07 / w (長度為10mm ) 。
  4. Having one direction along which double refraction of light does not take place. used of a crystal

    單軸晶體的有一個方向的,沿此方向不發生光的雙折射。用於晶體
