Abstract
A laser perforator is disclosed for perforating skin with a perforation to permit blood under a surface of the skin to flow out, the perforator in one embodiment having a laser light source for producing an output laser beam, and a mode distribution means for intercepting the output laser beam to control distribution of laser energy of the output laser beam across the perforation of the skin. A laser perforator is disclosed for perforating skin with a perforation to permit blood under a surface of the skin to flow out, the perforator in one embodiment having a laser light source for producing an output laser beam having an energy level between about 0.1 to about 2.0 Joules, and a mode distribution means for controlling mode distribution of the output laser beam across the perforation of the skin, the mode distribution means including a cylindrical laser rod to produce ring mode distribution of the output laser beam, the cylindrical laser rod having a 90 degree annular corner reflector to produce a ring mode distribution of the output laser beam, a doughnut lens for focusing the output laser beam, the perforation ranging in diameter between about 0.1 to about 2.0 millimeters, in dep…
