OK, so, really stupid question.
I've done what I can to read up about these things, with not much luck.
I just want to know- are they for mode correction or for FA correction?
Some say they simply fix the highly-divergent fast axis, while others have said they circularize the beam.
So what's the case with these, then? Do you need seperate optics after the prisms to get a round beam profile, or do the prisms also fix up the beam profile as well as correcting the fast axis?
Thanks in advance.
