Graphitized Layer Buried in a Diamond: SAW Generation under Picosecond Optical Excitation Journal of Physics: Conference Series, vol. 520, p. 012006, (2014)
аннотация

The excitation of SAW was detected on diamond with built-in ion-implanted graphitized layer under its illumination with femtosecond laser pulses. The spectral width of a SAW pulses were in the range of 1.5 2 GHz. It was found out that the anisotropy of the SAW propagation was practically absent. The increase in the implantation dose from 4 1015 cm-2 to 12 1015 cm-2 was shown to give rise to a dispersion of SAW propagation.
