Paper Abstract

The COIL has drawn considerable attention owing to its short, fiber-deliverable wavelength, scalability to very high powers, and nearly diffraction-limited optical quality. These unique abilities make it an ideal candidate for rapid cutting of thick metals and other laser materials processing applications. Cutting experiments have been conducted at the Air Force Research Laboratory Chemical Laser Facility for a number of metals including stainless steel, nickel, copper, titanium and aluminum. A simple model for the cutting performance has been very successful in predicting the cutting sped and depth for most of these materials. Different assumptions of this model produce very little effect on the model predictions at high cutting speeds an a small difference at very slow cutting speeds. Additional physical effects such as the effects of vaporization, which can be significant at slow cutting speeds when cutting very thick sections, is incorporated into the model. This paper demonstrates how various assumptions within the derivation of the model can lead to different forms of the scaling law.
