Abstract
Apparatus including a semiconductor laser source and means for stabilizing the frequency of the laser. A feedback signal is provided by means such as a Fabry-Perot interferometer, which signal is coupled simultaneously to two feedback loops. One loop provides high frequency control of the drive current while the other loop provides low frequency control of the laser temperature.
