if you're using 2007 or later version zemax, it's easy to get laser beam M-sqare: -JaC~v(0
{*`qL0u]^
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; 6jiVz%`=Z
%[-D&flKC
2) Tools --> Optimization --> Merit Function Listing: to open a text window display merit function; |JSj<~1 ki
R.!'&<Svq
3) Analysis --> Physical Optics -->POP: to set incident beam parameters like waist...., remember to Save your setting before POP analysis; Q~#udEajI
&2Q 4{i
4) You'll see M^2 on the Merit Function Listing window. e Fp4MD8?

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