“…So, we expect that cutting properties de®ned mainly by the absorption coef®cient are similar to those of YAG:Ho radiation [10±12]. Also the use of 1.32 mm wavelength has been reported in [9,13].…”

“…Recently the use of 1.44 mm wavelength has been reported in neurosurgery [8] and in resection of parenchymatous organs [9]. Laser radiation at 1.44 mm is a new one to use in ENT practice though the absorption coef®cient of a 26 cm À 1 of this radiation is close to the widely recognized YAG:Ho laser radiation (2.12 mm) [10].…”

In this paper, we consider a method of laser resection using the silica glass core from which the cladding layer has been removed as the cutting part of a laser scalpel. An absorbing layer coating the silica¯ber tip markedly alters its biotissue cutting characteristics. The results of histological studies of skin after exposure to a laser scalpel with and without a strongly absorbing coating (SAC) at a wavelength of 0.97 m show that resection using a coated scalpel is more sparing. When an uncoated scalpel was used, skin injury was more apparent in both its surface spread and the depth of structural damage, resulting in poorer tissue regeneration.

ObjectiveThe aim of this study was to analyze and evaluate 1.32-μm and 1.06-μm neodymium-doped yttrium aluminum garnet (Nd: YAG) lasers for use in liver and gastroepiploic vessel vaporization and coagulation.MethodsThe effects of 1.32-μm and 1.06-μm Nd: YAG lasers were compared for gastroepiploic vessel hemostasis in porcine liver.ResultsThe results were observed and measured under the same parameters and dose conditions. The 1.32-μm laser showed greater vaporization width and depth than the 1.06-μm laser. Both lasers controlled active bleeding. The coagulation band with the 1.32-μm laser was thinner than with the 1.06-μm laser, at nearly 3 mm. After cutting of 1- and 2-mm porcine vessels, no grossly visible bleeding was apparent. Intravascular thrombus was visible under the microscope. The length of vessel thrombosis in the experimental group was 2 mm and the diameter was 2 mm; the control group exhibited thrombi as 2.3-4.9 mm in length. Thrombosis completely blocked the blood vessels.ConclusionThe 1.32-μm laser had greater vaporization capability than the 1.06-μm laser and achieved hemostasis requirements for vessels less than 2 mm in diameter.
