Temporal dynamics of a ring dye laser with a stimulated Brillouin scattering mirror

We present a numerical study of the temporal dynamics of a stimulated-Brillouin-scattering ring resonator. A coaxial-flashlamp-pumped RH6g dye laser is assumed. The influence of the most important parameters on the temporal evolution of the resonator is analyzed, namely the acoustic decay time of the nonlinear material, the features of the external-injection pulse--its pulsewidth, energy, and spatial quality--and the coupling mirror reflectivity. The conditions to initiate and sustain laser oscillation in the ring resonator as long as the duration of the pumping-system pulse persists were found.
