用自由光谱范围为8 cm-1的法布里-珀罗涉仪测量了x=0.08、0.04和0.0(KDP)的混晶KDP_(1-x)DKDP_x的光散射谱。用声学声子耦合的偏振涨落的德拜型磁化率分析了光谱。当x=0.08，0.04和0.0时，孤立偶极子的驰豫时间分别为0.27，0.21和0.15，单位为10-12秒。
Light scattering spectra of mixed crystals KDP 1- x DKDP x with x =0.08, 0.04 and 0.0 (KDP) are measured by a Fabry-Perot interferometer with a free spectral range of 8 cm -1 . Spectra are analyzed with the Debye type susceptibility of a polarization fluctuation coupled to an acoustic phonon. The relaxation times of an isolated dipole for x =0.08, 0.04 and 0.0 are found to be 0.27, 0.21 and 0.15 in the unit of 10 -12 sec, respectively.
