Patent ID: 7780655

Claim:
A medical or cosmetic hand-held laser device, comprising: a light exit opening for emitting laser radiation onto a treatment area; a connecting device for connecting the hand-held laser device to a source for laser radiation; an optical waveguide device extending from the connecting device to the light exit opening, the optical waveguide device has a first section, a second section arranged at an angle to the first section, and a reflector arranged between the first and second sections with a substantially elliptical reflective surface for deflecting the laser radiation from the first section into the second section of the optical waveguide device and for creating an output cone of laser radiation emitted from the first section and a converging beam of laser radiation for receipt by the second section; the first section having a first end, opposite an end for receiving the laser radiation in the first section generated by the source, that penetrates a cavity of the reflector so that a first focal point of the reflector is within the first section and spaced apart from the first end, the first focal point being a tip from which the output cone of laser radiation is to be formed; the second section having a second end, opposite an end of the second section for emitting the laser radiation towards the treatment area, that is positioned with respect to the reflector surface so that a second focal point of the reflector is substantially coincident with the second end, so that the first and second sections are arranged differently with respect to their associated first and second focal points.
