title: Gouy wave modes: undistorted pulse focalization in a dispersive medium.
abstract: Gouy wave modes are linear waves with finite energy that propagate without distortion at any phase and group velocity through a focal region in a dispersive medium. These features make them potentially useful for the onset and control of nonlinear interactions.
