Numerical simulation of non-ablative laser texturing of silicon surface with a continuous wave fiber laser

Silicon is highly transparent to the infrared wavelength, so fiber laser with wavelength of 1090 nm is not regarded as a suitable tool for the purpose of ablation based surface texturing. However, we demonstrate, through finite element thermal analyses of laser irradiated surface, non-ablative textu...
