A new approach for a system and method for producing a substantially invisible medical tissue marker is described. In certain exemplary embodiments of the invention, the medical marker will become visible only when a light (energy) source is shined thereon. The visible action of the marker is accomplished, for example, utilizing materials that are multi-photon absorbers. In another exemplary embodiment, the medical marker will become visible for a given amount of time when the tissue marker is exposed to a specific light source.
