- W2321451535 abstract "The wavelength of Er: YAG laser is 2.94μm and this ability of incising biotissues is much stronger than CO2 laser (10.6μm). Furthermore, Er: YAG lasers cause much less thermal damage to biotissues than CO2 lasers, because Er: YAG lasers are more easily absorbed by water than CO2 lasers are. For studying possibilities of applying Er: YAG lasers to endoscopy, we tested fluoride glass fiber (ZrF4),chalcogenide glass fiber (As2S3) and hollow light guide all of which may be used in Er: YAG laser delivery system. The transmittance of the fluoride and the chalcogenide fibers we measured was 90% and 75% at 1m long, respectively. The test shows that these fibers are applicable to Er: YAG laser endoscopes, although the fibers have a fragile mechanism and some other problems yet to be solved. On the other hand, the transmittance of the Al hollow light guide measured 75% per meter. This hollow light guide may be too large to be used for endoscopy but it will be applied to surgical laser scalpels. We proposed the solid state laser of new type. This laser have the two kinds of GSAG host crystals which are doped with Cr and Nd, or Cr and Er. The wavelength of this laser are 1.06μm and 2.74μm, also this have photocoagulation and incision capability for biotissues." @default.
