    • th is on the order of microseconds for the IR and in the sub-microsecond range for the UV. These values are in both cases larger than the 7 ns duration of the laser pulses, and thermal confinement conditions are fulfilled, although to a lesser extent in the case of the UV pulses.

    • s within 1-3 ns are obtained. Because the 7 ns duration of the laser pulses applied in the present experiments lies within the same order of magnitude, partial stress confinment conditions might be expected in the IR-LDI process.
