An experimental-theoretical method of determination of 
the absorption coefficients in laser treatment of metals has been 
proposed based on the solution of the boundary-value axisymmetric 
problem of heat conduction for a half-space and metallographic measurements 
of the dimensions of the thermal-hardening zone.
