Beam with higher order dispersion

Hi Michael,

How can I make a beam with higher order dispersion etax2, etax3 included?

Thanks,
Farzad

Farzad,

We don't have a tool for that, but you can add it by hand. E.g.,

Code: Select all

sddsprocess beam0.sdds beam1.sdds \
 "-define=parameter,etax2,1,units=m" "-define=parameter,etax3,0.1,units=m" \
 "-define=column,delta,p pCentral / 1 -" \
 "-redefine=column,x,x etax2 delta sqr * + etax3 delta 3 pow * +,units=m" 
Of course, you'll also want to include the corresponding changes to the slopes, if any.
