It is well known that the advantage of endovenous laser therapy at 1470nm is the higher absorption coefficient of water compared to 980nm. Therefore, laser radiation can be applied precisely into the vein wall. Additionally, the process requires less total energy and generates lower heat.
The advantage of an endovenous laser therapy with 1470 nm is that the absorption coeffcient of water is 55 to 60 times higher at this wavelength than at 980 nm. Thus, a precise application of laser radiation into the vein wall can be performed. Furthermore, the treatment requires less total energy and shows lower heat generation.
Thanks to the constant technological evolution, the medical laser who is still the object of ceaseless improvements continuously has been applied in ENT surgery more and more up to now.
