Abstract
We report an ultranarrow-linewidth laser spectrometer at , consisting of a diode laser locked in a single stage to a stable high-finesse reference cavity. The system is characterized by comparison with a second independent system. From beat frequency measurements a linewidth below (FWHM) and a fractional instability of less than for of averaging time are observed.
