Subscriber请问在高斯光束的beam options 的标量近似法里,光束注入平面半径与光束发散角之间是有什么公式吗,以及它们与束腰半径的关系?十分感谢!

Ansys Employee光束注入平面半径与光束发散角和束腰半径没有物理联系,只是在仿真时要求它远远大于束腰半径,以免将物理光束截断。建议此数值10倍于束腰或者大于仿真区。

Subscriber感谢您的回复!还有一个问题是,采用Waist size and position时,waist radius w0一旦确定,distance from waist的变化是不会引起beam radius Wz 与divergence angle的变化,那distance from waist有什么作用嘛?

Ansys Employee我估计这是因为节省用户实际,divergence angle与waist radius w0有函数关系,而beam radius Wz 与beam radius Wz 和z 有函数关系。
我建议仅设置基本参数,divergence angle或waist radius w0,再加上注入平面到束腰位置的距离z就可以了,其它参数有内部函数关系计算。
