heal.abstract	An account is given of the study focusing on the role of the laser wavelength, the pulse duration, the energy fluence as well as the implications on the beam delivery means, the ablated surface modifications and the diagnostic techniques employed. It is experimentally verified that when using mid-infrared lasers with pulse durations in the ns range, the photothermal mechanisms involved exhibit strong absorption restricting the residual thermal damage to a relatively small zone. The ablation of tissue with ultrashort, picosecond and femtosecond, visible and near-infrared laser pulses is studied as an alternative. Further, the use of conventional and advanced microscopy, scanning electron microscopy (SEM) and atomic force microscopy (AFM) to study the surface and ends alterations of the delivery system involved and the surface alterations of the soft hard tissue target in pulsed laser ablation is detailed.	en
