[Controlled dermabrasion with a newly developed erbium-YAG-laser system. Report of preliminary experiences]

The reasons for the development of pulsed lasers, as well as the differences between them and continuous lasers are discussed. Both the advantages and disadvantages of such lasers, as well as the indications are presented. Furthermore, the erbium-yag laser is contrasted to the ultra-pulsed CO2 laser. Two case reports demonstrate the effectiveness of the erbium-yag laser.
