An atomic oscillator includes a gas cell, a semiconductor laser, and a frequency modulation signal generator generating a frequency modulation signal causing the semiconductor laser to generate frequency-modulated light including a first-order sideband light pair causing an electromagnetically induced transparency phenomenon in metal atoms. When a modulation level of frequency modulation changes from low to high, a modulation level at a time when the first-order sideband light is maximized for the first time is represented as m1, a modulation level at a time when intensity of light with a center frequency becomes equal to or higher than intensity of the first-order sideband light for the first time after decreasing to be lower than the intensity of the first-order sideband light for the first time is represented as m2, and intensity of the frequency modulation signal is set such that the modulation level is higher than m1 and lower than m2.
An atomic oscillator comprising:
A manufacturing method of an atomic oscillator, the atomic oscillator including a cell which encapsulates metal atoms therein, a light source which generates light for irradiation of the cell, a light detecting section which detects light transmitted by the cell, and a frequency modulation signal generation section which generates a frequency modulation signal for causing the light source to generate frequency-modulated light including a resonance light pair that causes an electromagnetically induced transparency phenomenon in the metal atoms, based on intensity of the light detected by the light detecting section, the resonance light pair being a first-order sideband light pair included in the light generated by the light source, the method comprising:
