Evolution of the damping time constant, τ. Damping time constant as a function of beam intensity for different frequency components (blue markers) of sample #1 SGL R6650 obtained from continuous wavelet analysis in comparison to the damping time constant (black line) of the radial surface velocity (a–f). Damping time constant of the radial surface velocity for samples #1 SGL R6650, #6 SGL R6650, and #3 POCO ZEE as a function of pulse intensity (b).
