THERMAL FIELD ON THE SURFACE OF A MATERIAL 
HEATED BY A LASER PULSE IN A NARROW RING 
OF ILLUMINATION

UDC 536.24+621.375

Based on a solution of the problem of the temperature 
effect of instantaneous heat sources uniformly distributed 
in a thin plane ring on the boundary of a semiinfinite 
body and different approximations of that solution, 
we constructed a dynamic model of a thermal field 
on the surface of a material heated by a laser pulse 
in a narrow ring of illumination.
