Photoacoustic Effect in Laser Annealing

Japanese Journal of Applied Physics, 1980
The acoustic wave generated in a silicon crystal during the laser annealing has been observed. The acoustic signal increases steeply with the incident laser energy beyond the melting threshold. This is explained by the increase of the optical absorption coefficient and the resultant increase of the temperature gradient in the sample accompanying the
