if you're using 2007 or later version zemax, it's easy to get laser beam M-sqare: +jpC%o}C
H-Z1i
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;
,1g*0W^
x tP=/B /
2) Tools --> Optimization --> Merit Function Listing: to open a text window display merit function; %Lwd1'C%
F W zf8*^
3) Analysis --> Physical Optics -->POP: to set incident beam parameters like waist...., remember to Save your setting before POP analysis; t?R=a- ZI
/o=,\kM
4) You'll see M^2 on the Merit Function Listing window. h2C1'+Q{9

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