  Rydberg-atom-enabled atomic vapor cell technologies show great potentials in
developing devices for quantum enhanced sensors. In this paper, we demonstrate
laser induced DC electric fields in an all-glass vapor cell without bulk or
thin film electrodes. The spatial field distribution is mapped by Rydberg
electromagnetically induced transparency spectroscopy. We explain the measured
with a boundary-value electrostatic model. This work may inspire new ideas for
DC electric field control in designing miniaturized atomic vapor cell devices.
Limitations and other charge effects are also discussed.
