then is it possible for you to prove z' = f(z^2 + z0^2 - fz)/(z - f)^2 + z0^2 ? the ABCD should be no problem. Just the algebraic don't how to prove it to be.

I am studying further about Gaussian optics. When Gaussian beam pass through a lens, the waist location is given by (z'-f) = (z-f)M^2 Where, z' is the waist location after lens, z is waist location before lens, f is the focal length of the lens M is the magnification. In Gaussian...
