WebFeb 19, 2024 · The combined one- and two-parameter bifurcation analysis uncovers globally diverse dynamical regimes (steady-state, oscillation, and chaos) in the solitary laser … Weba solitary diode laser is usually sensitive to optical feed-back. It was observed long time ago that return beam may induce oscillations that appear in the laser output intensity and their frequency varies with the cavity length, laser de-sign and operating conditions [4]. To achieve single frequency operation, a special wave-
