Atomic Clock and Atomic Magnetometer

Abstract

Todaythe Battery-operated clocks (quartz clock) with frequency instabilities of 10-11 can be used for time interval up to a day, and the package is not larger than 1 cm3, it could be widely used in portable electronic devices. In certain military and civilian applications, such as global positioning systems (GPS) and synchronization of mobile communication and navigation networks which demands timing precision and stability, that cannot be achieved with low-power quartz crystal technology which takes time intervals of more than a few minutes. Atomic clocks can provide these stabilities. Atomic magnetometer has extremely high sensitivity so along with atomic clock atomic magnetometer can also sense extremely low magnetic field so this device can also use in biomedical as well as defense field.
