  Cavalleri and coworkers have discovered evidence of light-induced
superconductivity and related phenomena in several different materials. Here we
suggest that some features may be naturally interpreted using a time-dependent
Ginzburg-Landau model. In particular, we focus on the lifetime of the transient
state in La$_{1.675}$Eu$_{0.2}$Sr$_{0.125}$CuO$_4$ (LESCO$_{1/8}$), which is
remarkably long below about 25 K, but exhibits different behavior at higher
temperature.
