if you're using 2007 or later version zemax, it's easy to get laser beam M-sqare: -':"6\W
5G'&9{oB
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; Jn[q<e"
g/l0}%
2) Tools --> Optimization --> Merit Function Listing: to open a text window display merit function; zh^jWu
we\b]
3) Analysis --> Physical Optics -->POP: to set incident beam parameters like waist...., remember to Save your setting before POP analysis; ~w1{zxs
"6E1W,|{
4) You'll see M^2 on the Merit Function Listing window. nI*(a:
n=G>y7b
In old version Zemax (before ver2007), M^2 is complicated to get, designer has to calculate manually. RUS7Z~5

Attached is a example, hope it be helpful. D]pK=247
