Laser perforator.

The invention relates to   a laser perforator for perforating skin comprisinga) a lasing element which emits a pulsed beam, optionally selected from the group consisting of Er:YAG, pulsed CO₂, Ho:YAG, Er:YAP, Er/Cr:YSGG, Ho:YSGG, Er:GGSG, Er:YLF, Tm:YAG, Ho:YAG, Ho/Nd:YAlO₃, cobalt:MgF₂, HF chemical, DF chemical, carbon monoxide, deep UV lasers, diode lasers, and frequency tripled Nd:YAG;b) a power source or ;c) a high voltage pulse-forming network linked to the power source;d) a means for exciting the lasing element , linked to the pulse-forming network ;e) a laser cavity ;f) a beam splitter [48] positioned to create multiple beams emanating simultaneously from the laser perforator, or optionally an acousto-optic modulator [52] outside the laser cavity , wherein the modulator consecutively deflects the beam at different angles to create different sites of perforation on the skin; andg) a focusing means which focuses each beam at a distance at least 10 mm from the lasing element and to at least one beam shaped as a closed conic section, wherein at the focal point of each beam one axis of the closed conic section is less than 1 millimeter.
