Abstract
Raman Scattering from a 7 nsec pulsed dye laser has been used to determine the onset of recrystallization following an 8 nsec dye laser excitation pulse in ion-implanted silicon. We find essentially complete recrystallization 59 nsec after the first excitation pulse and from Stokes-anti-Stokes ratios we find at 59 nsec a crystalline lattice temperature of 600 ± 200° C. Time-resolved transmission measurements at λ = 1.15 µm also demonstrate that no molten phase has occurred even though the usual reflectivity enhancement is observed.
