“…We believe this 'anomalous scale factor' regime can be theoretically described if one accounts for the non-zero relaxation time of the lower level of the laser transition (this time constant, which is typically on the order of a few tens of nanoseconds, is usually assumed to be equal to zero although it is comparable with the photon lifetime inside the cavity 1/γ ≃ 50 ns). The establishment of an absorption grating is likely to give rise to a low frequency beat signal [41].…”

We report experimental and theoretical study of a rotating diode-pumped Nd-YAG ring laser with active beat note stabilization. Our experimental setup is described in the usual Maxwell-Bloch formalism. We analytically derive a stability condition and some frequency response characteristics for the solid-state ring laser gyroscope, illustrating the important role of mode coupling effects on the dynamics of such a device. Experimental data are presented and compared with the theory on the basis of realistic laser parameters, showing a very good agreement. Our results illustrate the duality between the very rich non linear dynamics of the diode-pumped solid-state ring laser (including chaotic behavior) and the possibility to obtain a very stable beat note, resulting in a potentially new kind of rotation sensor.
