查询词典 quasi-permanent

According to the theory results,the two orthogonal polarized states of the fundamental mode become non-degenerate in this fiber and modal fields are quasi rectangular with appearing strongly linear polarization.And,the birefringence of the fiber was found to be due to the asymmetry of cladding structure.If the rate η between lognitudinal and transverse holes-spacing is reduced,the birefringence will increase strongly.

结果发现，矩形点阵微结构聚合物光纤基模两个正交偏振态不再简并，模场呈现类矩形且具有较强的线偏振特性；该光纤模式双折射产生于包层孔结构分布的不对称性，减小包层纵向孔间隔和横向孔间隔之比η值，双折射明显增强，适当调节η，可在更宽频带范围内实现高双折射单模运行。

A first order quasi phase matched periodically poled LiNbO 3 for SHG with 6.5 μm period, 12 mm length, 10 mm width and 0.5 mm thickness has been successfully fabricated by applying an external electric field at room temperature from an high pulsed voltage generator. About 18 mW of CW 0.532 μm green light was obtained pumped by an 1.1 W of CW 1.064 μm Nd∶YAG laser with end coupling, which corresponds to 1.6% power conversion efficiency.
