if you're using 2007 or later version zemax, it's easy to get laser beam M-sqare: !17Z\Ltqyj
c `; LF'!
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; W fNMyI
jy2nn:1#^
2) Tools --> Optimization --> Merit Function Listing: to open a text window display merit function; r/2:O92E
db~ :5#*
3) Analysis --> Physical Optics -->POP: to set incident beam parameters like waist...., remember to Save your setting before POP analysis; @NE#P&f
V~Lq, oth
4) You'll see M^2 on the Merit Function Listing window. b15qy? `y

In old version Zemax (before ver2007), M^2 is complicated to get, designer has to calculate manually. %MNV 5UA[w
