STUDIES OF AN OPTICALLY PUMPED RB87 MASER OSCILLATOR.
Abstract
An optically pumped Rb87 maser oscillator has been developed which produces a coherent microwave signal with power of 10 to the minus 10th power W at a frequency of 6835 Mc/sec. The oscillator has outstanding short-term frequency stability, is very compact, and does not require either a vacuum system, deflecting magnets, or an atomic beam. It is the first atomic frequency standard which is small enough and simple enough to be considered as a replacement for crystal oscillators. The device is about one cubic foot in size and consits of a microwave cavity filled with rubidium vapor and nitrogen buffer gas. The vapor is illuminated by rubidium resonance radiation from a simple discharge lamp. The effects of optical pumping, buffer gas, and temperature on frequency, gain, and bandwidth have been quantitatively determined. (Author)
