mx(x) = -0.5 * x2 / (z - x)
FD = z - LX; A : (z - mx)^2 = z^2 + (x - mx)^2; B : solve (A, mx)[1]; mx(x, z) := ''(rhs(B )); plot2d(mx(x, 25), [x, -15, 15], [y, -6, +6]) $

... while this can work with high quality gas- and NdYAG-lasers and pretty expensive fiber-lasers, 'adding height' or focus distance is really bad with laser-diodes - the beam quality is so poor, that with a focus distance of >70mm the shape of the spot will resemble not a round spot, but a line/rectangle with roughly 0.4mm x 0.1mm and even worser with growing distance
