Laser interaction with tissue depends on the wavelength of choice. The Triangel laser comes in 2 versions - the 980nm and the 1470nm.
1.The 980nm laser with equal absorption in water and blood, offers a robust all-purpose surgical tool, and at 30/60Watts of output, a high power source for endovascular work.
2.The 1470nm laser with significantly higher absorption in water, provides a superior precision instrument for reduced collateral thermal damage around venous structures.Accordingly, it is highly recommended for endovascular work.
