Optical and thermal fields used in laser annealing. (a) 2D optical profile of the laser line recorded at the sample position. (b) Transverse profile of illumination intensity profile, integrated over a 2-mm-wide central portion of the line. A fit to a Gaussian function is shown in red. (c) Silicon surface temperature profile across the laser line at 27 W of incident power recorded in vacuum. Data points obtained by melt-mark analysis and conventional thermocouple measurements are marked by black and blue circles, respectively. The red line is a guide to the eye. Full-width at half-maximum parameters are provided for both optical and thermal profiles.
