Nd3+:YAG laser interaction with intermetallic compounds Hf2Rh and Hf2Co

Abstract

The results of an investigation of Nd³⁺:YAG laser interaction with the intermetallic compounds Hf₂Rh and Hf₂Co are presented. The analytical expression for the laser pulse power is determined. Reflection spectra over a wide infrared region are measured to obtain the principal mechanism of absorption. The samples and the laser damage are investigated by the Taylor-Hobson Talysurf with a diamond needle for roughness measurements, optical microscope, scanning electron microscope (SEM) and electron microprobe analyses, and the results obtained are presented and discussed. Attention is paid to the validity of some principal relations characterizing the evaluation of the interaction.
