摘要： An atomic magnetometer that simultaneously achieves high sensitivity, simple fabrication and small size. This design is based on a diverging (or converging) beam of light that passes through an alkali atom vapor cell and that contains a distribution of beam propagation vectors. The existence of more than one propagation direction permits longitudinal optical pumping of atomic system and simultaneous detection of the transverse atomic polarization. The design could be implemented with a micro machined alkali vapor cell and light from a single semiconductor laser. A small modification to the cell contents and excitation geometry allows for use as a gyroscope.
摘要翻译： 同时实现高灵敏度，简单制造和小尺寸的原子磁强计。 这种设计是基于通过碱性原子蒸汽池并且包含光束传播矢量分布的发散（或会聚的）光束。 存在多个传播方向允许原子系统的纵向光泵浦和横向原子极化的同时检测。 该设计可以用微加工的碱性蒸汽池和来自单个半导体激光器的光来实现。 对细胞内容和激发几何的小修改允许用作陀螺仪。
