Abstract

This work has as main objective to develop a new source of diode laser compact and robust, beyond a new drive control for use in primary of time and frequency standards type cesium atom fountain and compact standards-based cold atoms. One of the requirements for the use of diode laser in primary of time and frequency standards are their stability in frequency and are very low spectral noise. Furthermore, given the embedded application, the laser must be extremely robust with respect to adverse conditions: mechanical, thermal and electrical. Both opto-mechanical part, as the electronic controls of the new laser were developed in this work. It is noteworthy that such a system, in its conception, is of great interest to many other types of applications such as spectroscopy of gases (LIDAR), references in other frequencies and experiments of atomic and molecular physics, which have high levels of demand with respect to spectral noise.
