Ab­stract:

In this ar­tic­le we pre­sent our physi­cal mo­del for in­ter­ac­ti­on of la­ser ra­di­a­ti­on with me­tals and al­loys thro­ugh struc­tu­ral chan­ges, mel­ting and va­po­ri­zing. We de­scri­be the in­ter­ac­ti­on of la­ser ra­di­a­ti­on with ma­te­ri­als, ki­ne­tic pro­cess of energy tran­smit­ting from free elec­trons to the crystal lat­ti­ce and pro­pa­ga­ti­on of he­at and the pro­ces­sing zo­ne. We con­si­der in­flu­en­ce of op­ti­cal and ther­mal pro­per­ti­es over ex­plo­ring pro­cess as they chan­ge with tem­pe­ra­tu­re and in the pre­sen­ce of mix­tu­res.

Keywords: physi­cal mo­del, la­ser, me­tals, al­loys, cha­rac­te­ri­stics.
