The physical principle of laser is the mutual effect between light and material. The energy produced by this effect can be precisely guided. This makes its use in biological materials results in tissue changes that can have therapeutic advantages. However, it should be noted that inappropriate use of radiation intensity invalidates and destroys the skills of surgeons. The aim of current study to study thermal and optical properties of human skin layers.
Thermal penetration depth (of human skin layers (Epidermis, Dermis and Fatty tissue) increased with increasing the time(t (seconds). Also, optical penetration depth (L/mm) of human skin layers (Epidermis, Dermis and Fatty tissue) was increasing with decreasing absorption coefficient(a/m). Moreover, increasing heating relaxation time () with decreasing the absorption coefficient ((m).
As it was observed that the thermal penetration depth value of human skin layers was increased with increasing the time. Therefore; increasing optical penetration depth values with decreasing absorption coefficient of the human skin layers (Epidermis, Dermis and Fatty tissue). Also, increasing the heating relaxation time with decreasing absorption coefficient of human skin layers.
