Paper Abstract

We have demonstrated that when using in surgical operations the radiation of YAG:Nd laser with 1.44 μm wavelength exhibits better cutting capabilities as compared to the same laser at 1.32 μm wavelength. The laser scalpel at 1.44 μm also provides adequate hemostasis at non-typical section of parenchymals without blood vessel ligation, however this capability is higher for 1.32 μm radiation. It is possible to combine the advantages of both radiations by repetitive switching the laser between two wavelengths or mixing two simultaneously generate wave in one optical waveguide. Application of several YAG:Nd laser wavelengths with different absorption coefficients in a single operation on the soft tissue allows one to coagulate large-scale blood vessels and to minimize thermal damages of surrounding tissue.
