  New results on the single-differential and fully-integrated cross sections
for the process $\gamma_{v} p \rightarrow p' \pi^{+} \pi^{-}$ are presented.
The experimental data were collected with the CLAS detector at Jefferson
Laboratory. Measurements were carried out in the kinematic region of the
reaction invariant mass $W$ from 1.3 to 1.825 GeV and the photon virtuality
$Q^2$ from 0.4 to 1.0 GeV$^2$. The cross sections were obtained in narrow
$Q^{2}$ bins (0.05 GeV$^{2}$) with the smallest statistical uncertainties
achieved in double-pion electroproduction experiments to date. The results were
found to be in agreement with previously available data where they overlap. A
preliminary interpretation of the extracted cross sections, which was based on
a phenomenological meson-baryon reaction model, revealed substantial relative
contributions from nucleon resonances. The data offer promising prospects to
improve knowledge on the $Q^{2}$-evolution of the electrocouplings of most
resonances with masses up to $\sim$1.8 GeV.
