So I have a HeNe laser, and I want to calculate the waist. I know how to calculate the divergence, using the knife edge technique, and I was under the impression that the waist could be calculated the same way.
I haven't been able to find too much info on it, however. Can anyone point me in the right direction?
Thanks!
