We report on the two-beamstudy of indirect excitons in the inner ring in the exciton emission pattern. One laser
beam generates the inner ring and a second weaker beam is positioned in the inner ring. The beam positioned
in the inner ring is found to locally suppress the exciton emission intensity. We also report on the inner ring
fragmentation and formation of multiple rings in the inner ring region. These features are found to originate from
a weak spatial modulation of the excitation beam intensity in the inner ring region. The modulation of exciton
emission intensity anticorrelateswith themodulation of the laser excitation intensity. The three phenomena—inner
ring fragmentation, formation of multiple rings in the inner ring region, and emission suppression by a weak
laser beam in the inner ring—have a common feature: a reduction of exciton emission intensity in the region of
enhanced laser excitation. This effect is explained in terms of exciton transport and thermalization.
