    摘要: An aspirating handpiece for laser surgical applications, includes an elongated hollow cylindrical probe member (22). A proximal end (24) of the probe member is arranged such that aspiration means can be connected therewith, and a distal end (26) of the probe member has an aperture therein for receiving matter to be aspirated. An elongated optical fiber (50) extends along the probe member with the distal end (59) of the fiber proximate the aperture therein. The proximal end (52) of the fiber is arranged to receive laser radiation. The probe member has an inside diameter progressively increasing from the distal end thereof to the proximal end thereof.

    摘要: A laser host material LuLF (LuLiF.sub.4) is doped with holmium (Ho) and thulium (Tm) to produce a new laser material that is capable of laser light production in the vicinity of 2 .mu.m. The material provides an advantage in efficiency over conventional Ho lasers because the LuLF host material allows for decreased threshold and upconversion over such hosts as YAG and YLF. The addition of Tm allows for pumping by commonly available GaAlAs laser diodes. For use with flashlamp pumping, erbium (Er) may be added as an additional dopant. For further upconversion reduction, the Tm can be eliminated and the Ho can be directly pumped.

    摘要: A composite multiple wavelength laser material is provided and is typically constructed with a common axis of construction in the form of a rod of uniform cross-section. The rod comprises a plurality of segments of laser material bonded, e.g., diffusion bonded, to one another along the common axis. Each segment lases at a unique wavelength when excited to produce a laser emission. The segments can be made from a birefringent material doped with laser active ions. If the same birefringent host material is used for all segments, ground-state absorption losses can be reduced by terminating either end of the rod with end segments made from undoped pieces of the birefringent material.
