if you're using 2007 or later version zemax, it's easy to get laser beam M-sqare: K ZFnp=i
*.X!AJ;M=O
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; !,f{I5/
YK[PC]w
2) Tools --> Optimization --> Merit Function Listing: to open a text window display merit function; W\V'o Vt
7B@[`>5?%L
3) Analysis --> Physical Optics -->POP: to set incident beam parameters like waist...., remember to Save your setting before POP analysis; &F4khga`^:
}P8@\2@=T
4) You'll see M^2 on the Merit Function Listing window. ?!R

!;";L5()
In old version Zemax (before ver2007), M^2 is complicated to get, designer has to calculate manually. >s yQDB
