Abstract: A treatment method for non-ablative tissue regeneration includes directing at least one laser pulse having a wavelength onto a tissue surface of a human or animal body, and controlling an energy delivery time ted of the at least one laser pulse, during which the second half of the pulse energy is delivered, to be sufficiently short, so that, given the wavelength and thus a corresponding penetration depth ? of the at least one laser pulse, a thermal exposure time texp of the tissue surface is smaller than 900 microseconds. The thermal exposure time texp of the tissue surface is defined as a time interval in which the temperature of the tissue surface is above To + (Tmax - To)/2, wherein To defines the initial temperature of the tissue surface, before the laser pulse arrives, and Tmax is a maximal temperature of the tissue surface.

Abstract: An apparatus for tissue regeneration is provided. The apparatus comprises means for generating at least one laser pulse comprising a wavelength; and means for directing the at least one laser pulse onto a tissue surface of a human or animal body, wherein the means for generating comprises control means to ensure that a sum of the pulse energies of the at least one laser pulse is selected so that the corresponding fluence on the tissue surface heats the tissue surface up to a maximal temperature Tmax between 70° C. and a tissue boiling temperature Tb. Further, the means for generating of the apparatus are adapted so that a delivery time ted of the at least one laser pulse (during which the second half of the pulse energy is delivered) is sufficiently short so that, given the wavelength and thus a corresponding penetration depth ? of the at least one laser pulse, a thermal exposure time texp of the tissue surface is shorter than 900 microseconds.
