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.

Abstract: The method includes the following step of forming at least one material input zone on the surface of an electrolyte, disposing a working tool in the input zone to push the material into the melt of the electrolyte, imparting mechanical oscillations and translatory motions to the working tool in the direction towards the electrolyte and back therefrom with the length of said motions being within the range of values from about 10.0 to about 120.0 sec. The method further includes transporting material into the input zone and forming some layer in the material input zone, and after accumulation of a sufficient amount of the material, the latter enters into contact with the working tool. The aforesaid steps increase the capacity of the material input zone and reduce power expenditures on the input of material into the electrolyte.

Abstract: A laser has been developed with an active laser element which, in certain aspects, employs no mirrors but instead has a lasant rod with ends formed to produce total or nearly total internal reflection and an output window surface at one end from which a laser beam exits the device. In one aspect a rod end or ends are formed in the shape of polyhedrons whose surfaces reflect oscillating radiation. Also disclosed is a laser with an active laser emitter with a lasant rod with a first end formed in the shape of a polyhedron and a second flat end adjacent to or in contact with a plate or plates of solid reflective, coated or uncoated material, which are next to each other or spaced apart by spacer apparatus, e.g. rings. Such a laser emitter may be used in a laser device without other mirrors or reflectors.
