Raman spectra of La$_{2-x}$Sr$_x$CuO$_4$ are similar to those of Bi$_2$Sr$_2$CaCu$_2$O$_{8+\delta}$ except for the split two-magnon peaks at the stripe phase and the stronger step-like decrease in the low energy $B_{\rm 2g}$ spectra. The suppressed $B_{\rm 1g}$ spectral region below the two-magnon peak decreases as the carrier density increases, whereas the energy of the step-like suppression is little dependent on the carrier density. It suggests the anisotropic charge transfer mechanism coupled with magnetic excitations along the nearest neighbor Cu sites and the phononic excitations along the diagonal direction.
