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; =e"H1^Ml
X; e`y:9
2) Tools --> Optimization --> Merit Function Listing: to open a text window display merit function; 1^n5CI|7u
8Cf ^$
3) Analysis --> Physical Optics -->POP: to set incident beam parameters like waist...., remember to Save your setting before POP analysis; ctnAVm
>FK)p
4) You'll see M^2 on the Merit Function Listing window. wFKuSd
