The exceptional efficacy of the 1940 nm laser is rooted in its unique physical characteristics. This wavelength aligns with the peak absorption band of water molecules, enabling highly efficient and rapid energy absorption within biological tissues. When the laser is delivered into the target area, its energy is instantly absorbed by the tissue's intracellular and extracellular water content, ensuring precise thermal action with superior clinical selectivity and minimal collateral damage.
1. Precision Energy Delivery: The 1940 nm laser beam penetrates the skin and is preferentially absorbed by intracellular and extracellular water within the target vein wall. This selective absorption ensures high photothermal efficiency with minimal dispersion into surrounding structures.
2. Direct Vessel Wall Closure: Laser energy is rapidly converted into heat. Unlike wavelengths targeting hemoglobin, thermal energy is concentrated directly on the venous wall. This results in instantaneous dehydration, collagen contraction, and coagulative necrosis, creating a precision photothermal weld that occludes the vessel.
3. Progressive Fibrosis and Clearance: The occluded vein undergoes fibrosis, transforming into a fibrous cord that is naturally resorbed by physiological metabolic processes over the following weeks to months.
