An unusual case of endobronchial Kaposi's sarcoma causing right middle and lower lobe atelectasis is reported. The lesion was successfully removed with Nd-YAG laser photoresection.

Introduction The Thulium fiber laser (TFL) is a new device that in contrast to the other solid-state YAG-based lasers takes different approach pulse formation allowing for two modes: QCW (quasi-continuous wave) function, TFL convenient soft tissue surgery and SP (Superpulsed) mode it highly effective lithotripsy. Thus, unlike thulium (Tm : YAG), can be used wide range of surgical procedures. Ma...

Single-crystal rare-earth doped YAG fiber lasers grown by the laser-heated pedestal growth technique Report Title High concentrations of the rare-earth elements erbium, holmium and thulium have been successfully doped into single crystal (SC) yttrium aluminum garnet (YAG, Y3Al5O12) fibers by use of the laser heated pedestal growth (LHPG) method. The spontaneous emission spectra and fluorescence...

introduction: the aim of this study was to evaluate the effect of dental surface treatment with erbium-doped yttrium aluminum garnet(er: yag), neodymium-doped yttrium aluminium garnet(nd: yag) and carbon dioxide laser  (co 2 ) lasers and sodium ascorbate to recently home bleached enamel by scanning electron microscope (sem). methods: thirty extracted human third molars were selected for this in...

ftr-raman spectra of human dental enamel, both laser-irradiated and untreated, are reported. spectra are compared with hydroxyapatite. it is evident that unlike the co2 laser, the nd/yag laser does not induce any chemical change in dental enamel.

This paper presents the results of a study of resonantly enhanced, three-, photon absorption in Nd-doped yttrium aluminum garnet (Y3Alg0~2) or Nd: YAG. The trivalent ions of the rare-earth elements, such as Nd'+, are characterized by energy levels which remain relatively sharp even in a crystalline environment, and thus crystalline solids doped with rare-earth ions present interesting systems i...
