摘　　要：用Z 扫描技术研究了各向同性手性介质 (聚酯酰亚胺吡啶溶液 )对于左、右圆偏振光的非线性圆双折射 ,得到在低光强下非线性旋光角的变化规律 ,验证了非线性圆双折射与非线性旋光的关系。By using the Z scan method, the nonlinear circular birefringence of an isotropic chiral medium (the pyridine solution of the polyesterimide ) for the left handed and right handed circularly polarized light is investigated. The law for the nonlinear optical rotation angle under the low light power is obtained. The relationship between the nonlinear circular birefringence and nonlinear optical rotation is verified.
