自然双折射 meaning in English

natural birefringence

Operating modes of ln one - dimension anisotropic aeo device and kdp two - dimension isotropic and anisotropic aeo device are determined . the principle to determine electro - optic operating mode is that the difference of two intrinsic diffractive index doesn ’ t contain nature birefringence and the acousto - optic operating mode should achieve a higher acousto - optic merit value to improve the efficiency
选择电光工作模式时,以所选取的电光工作模式的两个本征模之差不含有自然双折射量为最佳模式;选择声光工作模式时,以声光优值尽可能大为原则,以便提高器件的衍射效率。
