Fabric evaporation .. The rapid heat transfer from the laser light to the tissue leads to boiling in the cellular fluid and the complete rupture of the cellular protein and cell

Fabric steaming:
Occurs at temperatures higher than 100 ° C, especially with rapid heat transfer from laser light to tissue. This may lead to boiling in the cellular fluid and complete rupture of cellular protein and the cell itself.
The vapor of these vaporized tissues causes small atoms about one micron. It is therefore important to use a special laser mask during peeling or removal of skin lesions, especially viral lesions such as warts. Inhaling these vapors containing viral agents can cause serious complications. The laser mask must have a special specification for filtration of atoms and particles less than one micron.
The heat emitted directly depends on the interstellar medium of atoms, molecules, and excitation. When the temperature rises from 40100m, most proteins, DNA.RNA, membranes and cell contents start with fusion and coagulation.
Interference of the laser light with the treated tissue leads to thermal coagulation and thus causes cellular necrosis, vascular stenosis, fusion, closure of nerve endings and significant change in the material. Thermal coagulation is a burning and degenerating tissue.
The CO2 laser depends on the evaporation of the tissue water, as water is the target in such types of laser devices.
Some other lasers target skin pigmentation such as melanocytes, blood vessels and tattoo atoms.
The damage of the fabric depends mainly on the rate of radiation interference with the target, namely the extent of heat absorption or dispersion. The heat is absorbed by the chromophore, which is either melanin pigment, water or blood vessels, each of which has a specific elective length, affecting the particular type of Objectives.
Absorption depends on the concentration of the target material (Chromophore) in the tissue where the laser light is applied.
