摘　　要：生长了不同季氨盐掺杂浓度的 KDP晶体 ,其锥光干涉实验显示了晶体的内应力引起的双折射和双轴晶特性较明显。透过率特性的实验结果表明 ,不同浓度的季氨盐对 KDP晶体的光学均匀性有较大影响。报道了掺季氨盐 0 .0 0 1%的 KDP晶体的异常光学透过率特性以及晶体具有三维变化的波片效应和旋光特性。This paper presents the distinct characteristics of biaxial crystals caused by inherent stress using cone-shaped interference in the samples. The results of optical experiment show that the characteristics of light uniformity depend greatly on the concentrations of quaternary ammonium salt in solution. Supernormal transmittance ratio properties are reported of KDP crystals doped with 0.001% quaternary ammonium salt. These phenomena show that the wave-plane effect and the optical activity are highly displayed in KDP crystals, and the effect varies with the three-dimensional positions.
