Paper Abstract

High speed holography has been successfully utilized in observation of pulsed laser machining process. High speed holography is very powerful in recording high speed phenomena accompanied with strong self-luminance, as seen in the process of pulsed laser machining. In this paper, it is shown that vertical sectional shiape of drilled hole and splashed parti cles of molten metal in machining process could be recorded by using off-axis and in-line holography. From experimental results, many of the new aspects of laser machining process have become clearer.
