Patent number: 9031370Abstract: An optical fiber is disclosed which includes a protective outer jacket. The outer protective jacket is grooved to include one or more peripheral grooves formed into the jacket. In operation of a laser device, laser energy passes through the optical fiber to the distal tip of the optical fiber. As the distal tip erodes, the outer protective jacket also erodes in a controlled fashion such that portions of the outer jacket flake off as the fiber tip erodes to the position of the peripheral grooves formed in the outer jacket rather than in a random fashion.Type: GrantFiled: March 4, 2014Date of Patent: May 12, 2015Assignee: Lumenis Ltd.Inventor: Arkady Khachaturov

Patent number: 9017316Abstract: A system and method of estimating a distance between the distal end of an optical fiber and treated tissue, to improve treatment efficiency, is provided herein. The estimation is achieved by modulating the numerical aperture of a light beam transmitted through the fiber to receive reflections from the tissue and distinguish them from other reflections in the fiber, and further by calculating the distance by comparing reflection intensities of beams having different numerical aperture values that illuminate the tissue over a very short period, so that tissue and environment conditions do not change much. Distance estimation may be carried out by modulating the treatment beam itself, or by a light beam transmitted between pulses of a pulsed treatment beam.Type: GrantFiled: July 25, 2011Date of Patent: April 28, 2015Assignee: Lumenis Ltd.Inventors: Arkady Khatchaturov, Uri Voitsechov, Igal Koifman

Patent number: 8804779Abstract: A system, apparatus, and method may provide laser beams of two or more wavelengths from diode pumped solid-state laser sources (220, 222, 224). The beam paths of these laser beams with different wavelengths, which are generated by the laser sources (220, 222, 224), may be aligned along a common optical axis 280 by an optical configuration, to treat at least one target area. Frequency-doubled laser beams, output from a plurality of diode pumped solid state laser cavities, may be passed through fold mirrors (M2, M5, M8), and combined on a common optical axis 280, using one or more combiner mirrors (M10, M11, M12), to unify the beam paths.
