In this paper, based on quantum mechanics and photons theory, the characteristics, the light-wave mode, the excitated
radiation and the theory of light amplifying and producing are expatiated. The interactional process of laser and material
and their influences which are complex, fast, and multidimensional and with many parameters in the process are studied
using the model of mathematics-physics-mechanics. First, the calculate cell and calculate area are selected in reason, and
then the calculate areas are dispersed. Using combining steps function with linearity approximation, non-linear equations
are answered with the iterative method, the changing connections of temperature parameters are obtained, and the
surface intensify technique and processes are given which tradition technics cannot solve. It provides theory basic for
laser intelligent machining engineering.
