摘要: We study the features of optical rogue waves (ORWs) observed in an all-solid-state (Cr:YAG+Nd:YVO4) passively-Q-switched laser, which is a system wide practical interest. The extreme events appear as isolated pulses extraordinary intensity during chaotic regime this laser. standard theoretical description (three-level rate equations for single mode field and two-level absorber) does predict existence many dynamical features, including chaos, but it fails to ORWs. Faced with problem improving description, we find that ORWs are only when Fresnel number laser cavity embedding dimension attractor reconstructed from experimental time series high, spot profile has spatially complex structure. These results suggest spatial effects essential ingredient formation type
