Abstract :
A simple, compact, low-power physics package for a vapour-cell atomic clock is described. The device measures 6.6×16×1.3 cm and dissipates less than 30 mW of electrical power without thermal control. The instability is 1.3×10-10/√[τ/(s)] for integration times τ below 100 s. Applications for this device include distributed telecommunications systems, advanced Global Positioning System (GPS) receivers and laboratory instrumentation
