Under POP propagation you will see Beam Definition, under this tab you can define either the "Total Power" of the beam or the "Peak Irradiance". So the total power returns under the window (as you captured) will be reporting the total power with respect to the energy defined under this "Beam Definition". i;1aobG

選擇total power 和 peak irradiance會有什么不同呢，還有我想改變鏡子大小來看光的通過率，設(shè)定選擇surface type里的 aperture type 里的通光孔徑的大小，再看total power 的大小，這樣是不是可以說明不同半徑下光的通過率啊。

Whether choosing Total power or peak irradance, the energy/power of beam as a function of radius will just be calculated relatively to how you define it. So it shouldn't matter, and just depends on how the source beam is defined though (since the beam profile is there). cUssF%ud]

I think the method you proposed shall return the physical quantity you want to study. Hope this helps.

我想了解不同鏡子尺寸光的損失，不知道能不能通過看total power損失來研究呢

為什么不直接看透過率呢

Yes, Alien21 is right, you could check Polarization > Transmission as a way to check it, too. Iv,Ub_Ll9

If using POP, make sure you tick the box of "Use Polarization". So the total power shall account all sorts of energy loss.

謝謝樓主
