Transient temperature distribution on a finite domain induced by a dithering or rotating laser beam
MetadataShow full item record
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.
