Abstract
We have demonstrated wavelength tuning of diode lasers using precise temperature control. We have then stabilized the FM noise fluctuations of these lasers by using feedback control of the injection current. With these lasers and by using the saturation spectroscopy, we have resolved the Rb-D2 hyperfine absorption lines. We are using the hyperfine lines as frequency standard for stabilizing the laser. This work includes a comprehensive study of the Zeeman effect in Rb.
