However, the overall efficiency of this new technology is limited, in many instances, by the difficulty of obtaining effective coupling between incident laser radiation and the workpiece. High reflectivity, plasma shielding and gas absorption all conspire to reduce the overall coupling of

Experimental coupling coefficients for cw CO. laser radiation on metals over the range 20–1000°C are reported. The effect of oxidation on these coefficients is discussed. Finally, several methods of increa

Stimulated Absorption of C02 Laser Light on Metalse of initial surface roughness, which by a stimulated process grows into a coherent periodic corrugation or “ripple” pattern, owing to a nonlinear interaction with surface plasmons. Once developed, this ripple pattern acts as an anti-reflective coating, enabling the full absorption of the incoming r

Characterization of Laser-Induced Plasmas and Temperature Measurement During Laser Surface Treatmentting and vaporization as in laser surface alloying. Due to short dwell times, high temperatures and steep gradients, it is difficult to measure surface temperatures during laser/target interaction. Processes involving vaporization are more complicated to monitor due to the resulting plasma formation

One reason for this, of course, was the perceived technological importance of laser processing of silicon, which led to a broad-based, concentrated study of this problem. Furthermore, many
