Abstract

We have demonstrated a pair of counter-propagating superluminal Raman lasers without cross-talk, employing two different gain cells, each containing two isotopes of Rb, as a key step in realizing an ultrasensitive rotation sensor.

We used a numerical model, similar to the one used in ref. 6, to match the experimental results, as indicated by the solid curves. We employed a simplified four-level system for each isotope in this model. The matches are not perfect; further augmentation of the numerical model, taking into account the effect of all the hyperfine levels, is necessary to improve the agreement between theory and experiment. Using the numerical results, we also estimated the degree of enhancement in sensitivity for each direction, as shown in Fig. 2(B). The peak factor or enhancement in sensitivity in each direction is ~650. Fine tuning of the experimental parameters is needed to produce conditions that would yield a much higher sensitivity.
