Coherent interaction of mode locked lasers with 87Rb vapour is studied, for both two- and single-photon transitions. A ‘dark line’ is observed when the repetition rate of the laser is a submultiple of the ground state hyperfine splitting. The dark line resonance can be used for stabilization of mode locked lasers. Such stabilization has an impact on the development of sensors of extreme sensitivity. A new type of intracavity phase sensors is introduced: a purely optical accelerometer.

A rigorous quantum-mechanical treatment of the internally phase-modulated laser is performed in terms of traveling-wave modes of the quantized electromagnetic field. A detailed treatment of the modulation process is consistent not only with the phase-locked and FM behavior of the laser, but also describes the external (to the laser cavity) frequency shifting of phase-locked light and single-frequency ("super-mode") operation of the FM laser.
