我们报告了一种使用空心阴极灯将激光稳定到原子跃迁频率的可靠方法。与使用由纵向磁场引起的二向色性的标准二向色原子蒸气激光锁定（DAVLL）方法相比，我们采用由横向磁场引起的双折射。我们将此方法应用于 Sr 的 (5s2) S0− (5s5p) P1 跃迁 (461 nm)。尽管空心阴极由铁磁材料制成，但我们成功地施加了足够强度的磁场，以获得具有理论最大斜率的误差信号。该方法可以应用于不同原子种类的其他空心阴极灯。 © 2021 美国光学学会
We report a robust method of stabilizing a laser to the frequency of an atomic transition using a hollow cathode lamp. In contrast to the standard dichroic atomic vapor laser lock (DAVLL) method, which uses dichroism induced by a longitudinal magnetic field, we employ birefringence induced by a transversal magnetic field. We applied this method to the (5s2) S0− (5s5p) P1 transition (461 nm) of Sr. Although the hollow cathode is made of ferromagnetic material, we successfully applied a magnetic field of sufficient strength to obtain an error signal with a theoretical maximum slope. This method may be applied to other hollow cathode lamps of different atomic species. © 2021 Optical Society of America
