A non-stationary nonlinear axisymmetric model of the process of laser thermochemical processing of diamond has been developed. The values of temperature and diffusion coefficients in the three-phase system “hydrogen–metal–diamond” are calculated. The diffusion coefficients are determined and the diamond removal rate is estimated in the range of heat source power densities $q=10^4$–$10^7$ W/m$^2$ and metal coating thicknesses $h=10$ nm to $1$ $\mu$m.
