Research, using tandem satellites’ on-board tracking laser interferometers, is aimed at gauging the infinitesimal variations in the relative velocities of these orbiting bodies, to accurately measure fluctuations in earth’s gravitational field.A major part of this effort has involved the stabilization of semiconductor lasers’ frequencies to Fabry-Perot etalons and atomic absorption lines, and obtaining from them, the requisite control signal, by directly modulating the oscillation frequency. Taking advantage of the etalon’s short-term stability and tunability over a wide frequency range, and the Rb absorption line’s stability over the long term, we succeeded in stabilizing the frequency of a semiconductor laser. |
