Laser spider vein removal vascular therapy optical fiber 980nm diode laser 30W Theory of 980nm Diode laser vascular vein removal 1. 980nm laser is the optimum absorption spectrum of Porphyrin vascular cells. Vascular cells absorb the high-energy laser of 980nm wavelength, solidification occurs, and finally dissipated. 2. To overcome the traditional laser treatment redness large area of burning the skin, professional design hand-piece, enabling the 980nm laser beam is focused
