Dynamical behavior of multi-stripe laser array with external off-axis feedback

We report the results on the dynamical properties of broad area lasers with a V-shaped external cavity formed by two off-axis feedback mirrors. We derive and study a reduced model of a multi-stripe array under the influence of single and double feedback. In the bifurcation analysis we show the existence of single and multimode instabilities leading to a periodic and irregular time dependence of the output intensity.
