Abstract
Lugomer and colleagues have discovered filamentary-like coherent structures in small (â¼3Â mm diameter) laser-beam-metal-surface interactions. Experimental photographs of a small part of the laser spot area shows frozen “fossil” filament-like structures. We present reasonable arguments and preliminary computer results that suggest that these are due to vorticity deposited by accelerated flows due to blast and shock waves.
