During in situ laser-assisted micro-stamping (In-LAS) using a diamond indenter, the temperature of the machined area cannot be accurately predicted because of the coupling of the beam with the diamond indenter. This study uses geometrical optics and wave optics to determine the effect of the taper angle on laser direction, the light intensity distribution at the diamond indenter tip, and the temperature field of the machined area. This research provides data support and a theoretical basis for the selection of related process parameters of In-LAS and delivers a feasible theoretical method for a similar in situ laser-assisted machining.
