a Gaussian beam passes through a lens with focal length $f$, and then is incident upon a sample. The waist of the Gaussian beam (before passing through the lens) is at $z = 0$. The lens is located at $z =$ $l$. Assume that the input beam has $z_0 << l$. $2w_0$ $L$ $z = 0$ $z = l$ $Z$ $\text{focal length } f$ Calculate the lens focal length $f$ needed to ensure that Gaussian beam has a waist at the front surface of the sample. Show that for a given $l$ and $L$, two solutions for $f$ exist. Sketch the beam behaviour for each of these solutions
