  It has become clear that the anomalous properties of cuprate superconductors
are intimately related to the formation of a pseudogap. Within the framework of
the kinetic-energy-driven superconducting mechanism, the effect of the
pseudogap on the electronic Raman response of cuprate superconductors in the
superconducting-state is studied by taking into account the interplay between
the superconducting gap and pseudogap. It is shown that the low-energy spectra
almost rise as the cube of energy in the B_{1g} channel and linearly with
energy in the B_{2g} channel. However, the pseudogap is strongly anisotropic in
momentum space, where the magnitude of the pseudogap around the nodes is
smaller than that around the antinodes, which leads to that the low-energy
spectral weight of the B_{1g} spectrum is suppressed heavily by the pseudogap,
while the pseudogap has a more modest effect on the electronic Raman response
in the B_{2g} orientation.
