ABSTRACT:
An atomic frequency acquisition apparatus includes: a cell enclosing atomic gas therein; a laser light source that oscillates laser light that enters the cell and excites the atomic gas; and a photodetecting section that detects the laser light that has passed the cell, wherein the laser light source and the photodetecting section are attached to a common surface facing an interior of the cell, and the cell has a first reflection section on which the laser light oscillated from the laser light source is incident at an incident angle of 45 degrees, and a second reflection section on which the laser light reflected by the first reflection section is incident at an incident angle of 45 degrees.
