Abstract :
Summary form only given. We have developed a frequency stabilized laser system to supply light to measure atomic distance displacements of a stage moved in real time. Each laser in the array provides enough power (/spl sim/1 mW) for four Michelson interferometers whose accuracy requires a frequency stability of 20 kHz. In addition, each laser must be stable on both short and long time scales due to the real time control requirements.
