| 摘 要： | 测量了高强度三倍频实验的1ω 光和3ω 光的近场光束质量，将测量和模拟计算所得到3ω 光近场光束质量作了对比，重点对模拟计算得到的3ω 光近场光束质量所存在的误差进行了探讨，分析了现有的模拟计算程序中还未考虑到的影响3ω 光光束质量的主要因素，建议在以后的模拟计算程序中再进行优化设计，并讨论了改善3ω 光光束质量应采取的必要措施。

| Abstract: | 1w and 3 w near field beam quality for high intensity THG have been measured, and 3 w near field beam quality measured in experiments is compared with that simulated and calculated. Especially, the errors produced in simulation and calculation of near field beam quality for high intensity THG are investigated. By analyzing major factors not being considered that affect 3w near field beam quality in simulation and calculation, it is suggested that the simulating code be improved. Indispensable methods are discussed to improve 3w near field beam quality. The article is of reference value for further study on theories and experiments． |
