High power fiber laser outflow hole drilling apparatus and method of using high power fiber laser outflow hole drilling apparatus

摘要

A fiber laser machined workpiece is comprised of a body having a discontinuous surface that defines a plurality of spaced through passages, each of which comprises a cast layer or one or more microcracks or combinations thereof. Defined by a surrounding layer having surface characteristics to include. The path is provided by a high power Yb fiber laser that operates in a pulsed manner and is configured to output either a single pulse per entire path or a series of pulses per path. The Yb fiber lasers are configured such that when a cast layer and microcracks are each formed, they are smaller than their respective standards in the aerospace industry.
