Excitation of the in-plane Cu-O stretching phonon with a midinfrared pulse has been previously shown to induce a transient superconducting state in the closely related compound $La_{1.675}Eu_{0.2}Sr_{0.125}CuO_4$. In $La_{1.875}Ba_{0.125}CuO_4$, we find that the charge stripe order melts promptly on a subpicosecond time scale. Surprisingly, the low temperature tetragonal (LTT) distortion is only weakly reduced, reacting on significantly longer time scales that do not correlate with light-induced superconductivity. This experiment suggests that charge modulations alone, and not the LTT distortion, prevent superconductivity in equilibrium. 000307319 536__ $$0G:(DE-HGF)POF3-899$$a899 - ohne Topic (POF3-899)$$cPOF3-899$$fPOF III$$x0 000307319 536__ $$0G:(EU-Grant)319286$$aQ-MAC - Frontiers in Quantum Materials Control (319286)$$c319286$$fERC-2012-SyG$$x1 000307319 588__ $$aDataset connected to CrossRef 000307319 693__ $$0EXP:(DE-MLZ)NOSPEC-20140101$$5EXP:(DE-MLZ)NOSPEC-20140101$$eNo specific instrument$$x0 000307319 7001_ $$0P:(DE-HGF)0$$aTobey, R.
