POP传输有能量和位相的输出，找了半天没有发现光束质量因子M2的输出。难道要自己手算？

toobug1,

if you're using 2007 or later version zemax, it's easy to get laser beam M-sqare:

1) Editors --> Merit Function:  to edit the merit function Type=POPD, Data=25 OR 26 for beam M^2;  set Surf, Wave,Field per your system configuration;

2) Tools --> Optimization --> Merit Function Listing:  to open a text window display merit function;

3) Analysis --> Physical Optics -->POP: to set incident beam parameters like waist...., remember to Save your setting before POP analysis;

4) You'll see M^2 on the Merit Function Listing window.

In old version Zemax (before ver2007), M^2  is complicated to get, designer has to calculate manually.

Attached is a example, hope it be helpful.

Let me know how thing's going.
