Publication number: 20140225678Abstract: An atomic oscillator includes an alkali metal cell encapsulating an alkali metal atom; a light source that emits laser light; a light detector that detects light which has passed through the alkali metal cell; and a polarizer arranged between the alkali metal cell and the light detector. A modulation frequency in the light source is controlled, according to a coherent population trapping resonance which is a light absorption characteristic of a quantum interference effect for two kinds of resonant lights, by modulating the light source to generate sidebands and injecting laser lights with the sidebands into the alkali metal cell. A magnetic field is applied on the alkali metal cell in a direction parallel to a propagating direction of the laser light, and the laser light entering the alkali metal cell has a linear polarization, which is not parallel to a polarization direction of the polarizer.Type: ApplicationFiled: February 10, 2014Publication date: August 14, 2014Applicants: TOKYO METROPOLITAN UNIVERSITY, MUNICIPAL UNIVERSITY CORP., RICOH COMPANY, LTD.Inventors: Yuichiro YANO, Shigeyoshi GOKA
