Abstract
We show that a large portion of it forms a cloud of small particles long time residing in surrounding atmosphere. The cloud can effect ablation by following laser pulses introducing low-threshold plasma ignition. The resulting plasma screening is especially pronounced in long channels, where convection is poor and retardation of drilling rates reaches two orders of magnitude.
