THEORETICAL DESCRIPTION OF HIGH ORDER PARAMETRIC PROCESSES IN CAPILLARY

提出了毛细管中高阶光学参量过程的理论模型 .该模型在传统的高阶参量过程理论模型的基础上 ,自洽地考虑了毛细管中光学导波模式特征和激光束对毛细管中光学导波模式激发效率的影响 ,得到了毛细管中高阶光学参量过程的相位匹配条件 .利用这个理论模型概略地分析讨论了毛细管中高阶光学参量过程的最近的实验结果 .

A theoretical model of high-order parametric processes in c ap illary is proposed. Based on the conventional theory of high order parametric pr ocesses and taking the effects of guidewave modes in capillary and the couple ef ficiency of the laser beam with the guidewave into account consistently, a phase match condition of the high order parametric processes is obtained. As a prelim inary application of the above theory, a brief discussion about the recent exper imental results on high order parametric processes in capillary is given.
