Laser materials processing with dynamic-beam parameters in the focus region

This paper reports on a new arrangement for laser materials processing allowing the fast variation of beam parameters in the focus region, e.g., the polarization of the radiation and the diameter and position of the focus spot. Results of CO2 laser cutting of mild steel with a dynamic polarization are discussed.© (1993) COPYRIGHT SPIE--The International Society for Optical Engineering.
