weak light field

Using wave guide theory, we deduce scalar approximate solution about transmissive light through a fiber weak-guide and give the expressions of field in each component.

根据光波导理论，推算出弱导条件下光沿光纤传输场的标量近似解，给出场的各分量表达式，以便分析讨论。

With the increase of the dipole-dipole interaction between atoms, the squeezing effect of light field gradually becomes weak and the squeezing time gradually decreases.

原子之间的偶极-偶极相互作用的增加，光场的压缩效应，逐渐变弱，挤压时间逐渐减小。

In the end, the applications of infrared CCD, ultraviolet CCD and weak-light CCD in the observation of sun magnetic field and sun stellar magnetic field are introduced.

本文最后还对红外CCD、紫外ccd、弱光CCD在太阳磁场测量和太阳恒星磁场观测的应用进行了介绍。
