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; ajkRL|^

2) Tools --> Optimization --> Merit Function Listing: to open a text window display merit function; x8zUGvtQ
G+\2Aj
3) Analysis --> Physical Optics -->POP: to set incident beam parameters like waist...., remember to Save your setting before POP analysis; -f Zm_FE
5OKbW!
4) You'll see M^2 on the Merit Function Listing window. 2,NQ(c_c$

In old version Zemax (before ver2007), M^2 is complicated to get, designer has to calculate manually. 9.1%T06$
