Paper Abstract

Since a few years, atomic pumping technology has spread a lot, in particular for applications like very sensitive and stable atomic clocks, gyrometer, gradiometer, and gravimeter. Development of a compact optical source with a high power and a very narrow linewidth has become very important. At the moment, using an extended cavity laser (ECL) is a common solution in laboratory. For integrated system in spaces applications which need an excellent mechanical stability, the distributed feedback laser diode could be a good alternative. In this paper, we will present the performances of two kinds of lasers: Fabry-Perot laser diode (FP) and distributed feedback laser diode (DFB), centered at 780nm, for the pumping of the D2 line of Rubidium atoms (Rb). The Fabry-Perot laser diode presents the advantage of a high power emission but with a multimode optical spectrum. It can be integrated in an extended cavity which permits to filter the frequency and therefore to obtain a very narrow linewidth (less than 100 kHz). The DFB laser has the advantage to show a single frequency emission thanks to the integration of the filter in the device waveguide.
