Why is the 980nm and 1470nmfiber laser significantly improved for varicose vein treatment?

In the treatment of varicose veins using the lightivated instrument, the 1470nm wavelength laser achieves rapid contact vaporization and coagulation in the middle of the blood vessel. At the same time, the thermal effect of the 980nm laser on the target tissue is used to achieve non-contact solidification of the inner wall of the blood vessel, thereby solving the problem that the single wavelength cannot realize the middle and inner walls of the blood vessel. The drawbacks of not being able to coagulate rapidly at the same time, so that the curative effect is significantly improved, and the recurrence of the disease is greatly reduced.
