Abstract：
:The objective of this study was to describe the dynamics of water heating carried out by continuous laser radiation with wavelengths 1.47, 1.55, and 1.94 μm with different types of fibers used for endovenous laser coagulation. The study was conducted in water using high-speed surveying of the heating process through the shadow optical method. It has been shown that in the case of highly water-absorbed laser radiations, convection and boiling play a major role in the process of heat transfer. It has been shown that in the case of radiation with λ = 1.94 μm that is heavily absorbed by water, effective heat transfer begins at significantly lower levels of power compared to the weaker-absorbed radiations with λ = 1.47 and 1.55 μm. Mathematical models based only on thermal conductivity inadequately describe the process of real heat transfer during endovenous laser coagulation. It has been established that heat transfer is sharply asymmetrical and is directed mainly up-and-forward (bare-tip fiber) or upward ("radial" and "two-ring" fibers). Heat transfer for laser light with wavelength 1.94 μm is most effective than for 1.47 and 1.55 μm.
