Abstract
A new laser perforator has been invented 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 apparatus 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, the perforation ranging in diameter between about 0.1 to about 2.0 millimeters, in depth between about 0.5 to about 4.0 millimeters, and ranging in width between about 0.05 to about 0.2 millimeters. A method is also disclosed for perforating skin for blood sampling.
