Abstract : This patent discloses an extended laser sensor including a laser with an optical gain lasing medium optically coupled to an optical resonant cavity including reference and sensor arms. Optical path length variations in the sensor arm induced by an incident physical field moderate the operating parameters of the laser. The field is sensed by monitoring these modulated operating parameters.
