STABILITY CONSIDERATIONS FOR A RB87 MASER OSCILLATOR.
Abstract
Self-sustained oscillation was obtained in an optically pumped rubidium maser operating at the Rb87 hyperfine transition frequency of 6835 Mc/sec. The entire apparatus can be mounted within the volume of one cubic foot. The operating temperature is 60C, and the overall power consumption is only a few watts. The anticipated longterm stability is one part in 10 to the 12th power. Preliminary estimates also indicate that the device has far better short-term stability than any other existing frequency standard. The present paper explains the basic principles of the rubidium maser and examines the factors affecting the stability of oscillation. (Author)
