abstract = {We analyze the pump wavelength dependence for the
photoinduced enhancement of interlayer coupling in
$La_{1.885}Ba_{0.115}CuO_4$, which is promoted by optical
melting of the stripe order. In the equilibrium
superconducting state (T <TC = 13 K) in which stripes and
superconductivity coexist, time-domain terahertz
spectroscopy reveals a photoinduced blueshift of the
Josephson plasma resonance after excitation with optical
pulses polarized perpendicular to the CuO$_2$ planes. In the
striped nonsuperconducting state (TC < T < TSO ≃ 40 K) a
transient plasma resonance similar to that seen belowTC
appears from a featureless equilibrium reflectivity. Most
strikingly, both these effects become stronger upon tuning
of the pump wavelength from the midinfrared to the visible,
underscoring an unconventional competition between stripe
order and superconductivity, which occurs on energy scales
far above the ordering temperature.},
