   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.

   We assume that a coherent phonon generation was found out in structures with a single graphitized layer under picosecond laser excitation by means of the Pump/Probe method. The thermal component of the response was calculated that allowed us to define the photothermal coefficient of the graphitized layer as well as its thermal conductivity from the experimental results. The thermal-conductivity coefficient of the graphitized layer appears to grow with the thickness decrease. This makes it possible to assume that the microstructure of the graphitized layer produced during annealing depends on its thickness. iopscience.iop.org/article/10.1088/1742-6596/278/1/012019
