Abstract

The frequency stabilization of a semiconductor laser has usually been performed by applying a small modulation directly to the injection current. This paper reports a few frequency stabilization methods without a direct modulation, i.e., without a frequency broadening. These stabilization methods use the Faraday effect and/or the Zeeman effect of a saturated absorption line of the Rb atoms to obtain a control signal which is feedback to the injection current. These methods provide a better frequency stability and frequency control compared with the method using the direct modulation.
