The mathematical model for description of the processes of heat-and-mass transfer un-
der the pulsed laser exposure is proposed. It consists of heat and diffusion problems taking
into consideration the nonlinear dependence of the carbon diffusion coefficient on temperature and concentration. In consequence, we have obtained the distribution of the temperature and concentration
fields in the laser exposure range. An explanation of the formation mechanism for the oscillation structure of the carbon concentration distribution in the sample depth is proposed.
