摘要：
We report certain complex behaviors of a nanosecond Nd: YAG laser produced plasma on a Ni target. For high laser fluences, a split in the transversal expansion plane along with oscillatory regimes of the ablation plasma were observed and investigated. These complex phenomena, which take place at various interaction time scales, are described using a fractal theoretical model based on continuous but non-differentiable curves of particle movement.
