We study the response of the one-dimensional charge density wave in K0.3MoO3to different types of excitation with femtosecond optical pulses. We comparethe response to direct excitation of the lattice at mid-infrared frequencieswith that to the injection of quasi-particles across the low-energy chargedensity wave gap and to charge transfer excitations in the near infrared. Forall three cases, we observe a fluence threshold above which the amplitude-modeoscillation frequency is softened and the mode becomes increasingly damped. Weshow that all the data can be collapsed onto a universal curve in which themelting of the charge density wave occurs abruptly at a critical latticeexcursion. These data highlight the existence of a universal stability limitfor a charge density wave, reminiscent of the empirical Lindemann criterion forthe stability of a crystal lattice.
