Abstract :
Optical state preparation and detection are discussed and used to explain the potential benefits and limitations of optically pumped primary frequency standards. The potential of these standards for accuracy is outlined. An atomic beam tube design is briefly described. Limitations on achievable performance resulting from laser FM noise problems and some solutions are outlined. Some of the requirements on supporting electronics which control the clock frequency and other parameters are discussed
