We report femtosecond resonant soft X-ray diffraction measurements of thedynamics of the charge order and of the crystal lattice in non-superconducting,stripe-ordered La1.875Ba0.125CuO4. Excitation of the in-plane Cu-O stretchingphonon with a mid-infrared pulse has been previously shown to induce atransient superconducting state in the closely related compoundLa1.675Eu0.2Sr0.125CuO4. In La1.875Ba0.125CuO4, we find that the charge stripeorder melts promptly on a sub-picosecond time scale. Surprisingly, the lowtemperature tetragonal distortion is only weakly reduced, reacting onsignificantly longer time scales that do not correlate with light-inducedsuperconductivity. This experiment suggests that charge modulations alone, andnot the LTT distortion, prevent superconductivity in equilibrium.
