Transient temperature distribution on a finite domain induced by a dithering or rotating laser beam
ZT_DEPS_11.pdf (865.4Kb)Abstract
We obtain the temperature distribution due to a rotating or dithering Gaussian laser
beam on a finite body numerically by solving one-dimensional, two-dimensional and three dimensional nonhomogeneous transient heat equation with various techniques. Our main
result is that the maximum temperature rise decreases with increasing frequency of the
rotating or dithering beam. It is also found that the maximum temperature rise behaves
asymptotically as 1/frequency in the 1D and 2D cases whereas in 3D the maximum temperature rise acts aymptotically as 1/ square root of frequency.
