Abstract

The laser beam absorption lengths of CO₂ and a high power diode laser (HPDL) radiation for concrete have been determined. By employing Beer-Lambert's law the absorption lengths for concrete of CO₂ and a HPDL radiation were 470 ± 22 μm and 177 ± 15 μm, respectively. Indeed, this was borne out somewhat from a cross-sectional analysis of the melt region produced by both lasers which showed melting occurred to a greater depth when the CO₂ laser was used.
