[求助]请问在Zemax在哪里查看M2 [复制链接]

请问在Zemax在哪里查看M2，谢谢！

POP传输有能量和位相的输出，找了半天没有发现光束质量因子M2的输出。难道要自己手算？

if you're using 2007 or later version zemax, it's easy to get laser beam M-sqare: qrdA4S

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; A<$~Q;r2a  
.:dy d  
2) Tools --> Optimization --> Merit Function Listing:  to open a text window display merit function; #7(?B{i  
ZDn5d%  
3) Analysis --> Physical Optics -->POP: to set incident beam parameters like waist...., remember to Save your setting before POP analysis; T)N_~f|

4) You'll see M^2 on the Merit Function Listing window. oJ4OVfknD

In old version Zemax (before ver2007), M^2  is complicated to get, designer has to calculate manually. A?)nLp&Y

谢谢！mang2004！ ?Sj>b  
可惜我用的是2003版的。2003版pop没有data 25 26，且近轴只能看到基模的束腰和发散角。那么，2007版是如何计算的呢？

嗯   是popd运算元里有？

來看看

很高深的样子

Thanks!!

Very nice! Thanks!
