本文用90度布里渊散射光谱测定了室温下ZnTe晶体的弹性和光弹常数。从测量的布里渊双重峰的频率偏移，获得以下值的弹性常数：C11=7.22+或-0.02，C12=4.09+或-0.06和C44=3.080.03，单位为1010 N m-2。通过比较在ZnTe中测得的布里渊双重峰的绝对强度与已知光弹常数的熔融石英中的布里渊双重峰的绝对强度，确定了光弹常数的以下值：P11=0.144+或-0.007，P12=0.094+或-0.005，P44=0.046+或-0.003。
The elastic and photoelastic constants of ZnTe crystals have been determined from Brillouin scattering spectra with 90 degrees -scattering geometry at room temperature. From the measured frequency shifts of the Brillouin doublets, the following values are obtained for the elastic constants: C11=7.22+or-0.02, C12=4.09+or-0.06 and C44=3.080.03 in units of 1010 N m-2. From the comparison of the absolute intensities of the Brillouin doublets measured in ZnTe with that in fused quartz whose photoelastic constants are well-known, the following values are determined for the photoelastic constants: P11=0.144+or-0.007, P12=0.094+or-0.005 and P44=0.046+or-0.003.
