Abstract
A single-mode GaAlAs diode laser has been frequency stabilized by keep ing the injection current and the voltage across the laser constant. T he stability of the laser was studied by heterodyning it with another laser locked to the center of a hyperfine transition of the D2-line of Rb-85. Alternatively, the frequency stability was observed by tuning the voltage-controlled diode laser to the center of an absorption line of rubidium vapor and recording changes in the absorption signal. In both cases a long-term frequency stability of 4 . 10(-8) was observed.
