A low-power c-w hf/df chemical laser, designed to achieve high-frequency stability has been built. Measurements are reported which characterize the instantaneous spectral width of the laser output to less than one part in 10/sup 11/ (..delta nu.. < 1 kHz) and the variations in absolute frequency of this emission with time to four parts in 10/sup 10/ (..delta nu.. = +-20 kHz) per 0.1 ms. Two experiments to actively stabilize the laser frequency are reported. In one experiment the laser was locked to a high-finesse Fabry--Perot to five parts in 10/sup 9/ (..delta nu.. = +-250 kHz) for many minutes. In the other experiment one laser was locked to another using heterodyne beat spectroscopy to 1.7 parts in 10/sup 9/ (..delta nu.. = +-85 kHz). The stabilization experiments were limited by the feedback loops used.
