| 摘 要： | 研究了双轴晶体中通过非简并四波混频产生可变频的共轭波.在KTP中共轭波有各种匹配类型.若选择合适的匹配方向及泵浦和探测波矢的合适角度,使由于离散效应引起的所有光线之间偏离得到最好的补偿.从而增加晶体的有效长度,并显著改善能量的转换效率,得到各种匹配类型的最佳工作条件.

| Abstract: | The frequency varied conjugation wave generation by nondegenerate four wave mixing is investigated in biaxial crystal. The conjugation wave generation has various matching types in KTP . If the matching directions and the angle between pump and probe wavevectors are properly selected , the deviation between all rays with walkoff effect can obtain the most optimum compensation . The effective length of crystal is increased and the energy conversion efficiency is greatly enhanced. The corresponding optimum operation for each matching type will be found. |
