摘要：
A quantum interference device has an atomic cell which has alkali metal atoms disposed within. A light source emits light to excite the alkali metal atoms in the atomic cell. An optical element is disposed between the light source and the atomic cell, and enlarges the radiation angle of light emitted from the light source. A light detector detects light transmitted through the atomic cell.
