Paper Abstract

Recent advances in laser diode pumped solid state laser sources permit the design and testing of laser sources with linewidths that approach the Schawlow-Townes limit of 1 Hz/mW of output power. Laser diode pumped solid state ring oscillators have been operated with cw output power levels of 25 mW at electrical efficiencies that exceed 6%. These oscillators are expected to operate for lifetimes that approach those of the laser diode sources which is now approaching 20,000 hours. The efficiency and lifetime of these narrow linewidth laser sources will enable basic physics space measurements of gravity waves, remote sensing applications including local range rate and LIDAR measurements, and laser sources for frequency and time standards. A free-flight experiment called SUNLITE (Stanford University NASA Laser In-space Technology Experiment) is being designed to measure the linewidth of this all solid state laser system.
