Abstract
The in vitro dynamics of the change in optical properties of hyaline cartil age heated by fibre lasers at wavelengths 0.97 and 1.56 mum is studied. The laser-induced bleaching (at 1.56 mum) and darkening (at 0.97 mum) of the c artilage, caused by the heating and transport of water as well as by a chan ge in the cartilage matrix, were observed and studied. These effects should be taken into account while estimating the depth of heating of the tissue. The investigated dynamics of light scattering in the cartilage allows one to choose the optimum radiation dose for laser plastic surgery of cartilage tissues.
