| 摘 要： | 建立了描写皮秒激光在充气毛细管中四波混频过程的耦合方程组．利用这个耦合方程组对最近的毛细管中差频过程的实验结果给出了新的理论说明．发现采用三阶非线性极化率大的介质是进一步提高信号光强度的重要途径．

| Abstract: | The coupled equations for four wave mixing in gas filled capillary are described. Based on the coupled equations, a new theoretical explanation of the recent experimental results on the four wave mixing in gas filled capillary is given. It is found that to use material with large third order susceptibility is an important approach to increase the signal intensity. |
