if you're using 2007 or later version zemax, it's easy to get laser beam M-sqare: cFagz* !
dk==?
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; R <"6ojn
nCKbgM' "
2) Tools --> Optimization --> Merit Function Listing: to open a text window display merit function; pfd# N[c
A`u$A9[
3) Analysis --> Physical Optics -->POP: to set incident beam parameters like waist...., remember to Save your setting before POP analysis; 6UE(f@
"|m|E/Z-9
4) You'll see M^2 on the Merit Function Listing window. =D^TK-H

In old version Zemax (before ver2007), M^2 is complicated to get, designer has to calculate manually. IAOcKQ 3
