Abstract

The laser beam absorption lengths of CO2 , Nd:YAG and a high power diode laser (HPDL) radiation for a newly developed SiO2 /Al2O3 -based tile grout have been determined through the application of Beer-Lambert's law. The findings revealed marked differences in the absorption lengths despite the material having similar beam absorption coefficients for the lasers. The absorption lengths for the SiO2 /Al2O3 -based tile grout for CO2, Nd:YAG and HPDL radiation were calculated as being 232±11, 193±4 and 183±8 μm, respectively. Moreover, this method of laser beam absorption length determination, which has hitherto been used predominantly with lasers operated in the pulsed mode, is shown to be valid for use with lasers operated in the continuous wave (CW) mode, depending upon the material being treated.
