Abstract

The frequency stabilization of an AlGaAs laser using the linear optogalvanic signal from metallic vapor is reported. A hollow-cathode discharge tube, designed and built in our laboratory, has been used to obtain resonant optogalvanic lines corresponding to Ul and Thl transitions. These results show that the rich optogalvanic spectra of Ul and Thl can be efficiently used for the frequency-locking of semiconductor lasers.
