Scatter Plot from Scientific Research

Fluence dependence of the relaxation time (top) as well as the order parameter value in the quenched and quasi-thermalized stage (bottom). At a fluence of F th = 0.5 mJ cm − 2 , the quenched PLD amplitude exhibits a distinct kink, and the relaxation time relax is largely independent of the fluence beyond this threshold. Circle diagrams illustrate the quenched and relaxed amplitudes of both contributions to the order parameter. The smaller, excitonic component is particularly soft; that is, during the quench it is already fully suppressed at F th . Error bars in the top panel indicate 1 σ confidence intervals of the fitted relaxation time.
