Abstract: From the intensity ratio of the folded longitudinal acoustic phonons with re-spect to the longitudinal acoustic phonon in a Ge0.51Si0.49/Si superlattice (SL),we obtained a photoelastic constant. ratio of 6.6 for Ge0.51Si0.49 alloy with re-spect to Si in the SL at wavelength 5145Å, which is 2.6 times greater than that obtainedby [He Phys.Rev. B39(1989) 5919] in a Ge0.51Si0.49/Si SL.
