Figure 2

The coordinate system and notations are defined. The membrane is in the x–y plane and undergoes small displacements in the z direction. The membrane is positioned such that its average z position, h0, is at the inflection point of the intensity distribution, I(z). ω0 and z0 are the radii of the beam waist in the radial and axial directions, respectively.
