Determination of absorption length of CO2 and high-power diode laser radiation for ordinary Portland cement

摘要

The laser beam absorption lengths of CO2 laser and a high-power diode laser (HPDL) radiation for the ordinary Portland cement (OPC) surface of concrete have been determined. By employing Beer-Lambert's law the absorption lengths for concrete of the CO2 laser and the HPDL radiation were 470 +/- 22 mu m and 177 +/- 15 mu m, respectively. [References: 14]
