Si is highly transparent to infrared fiber laser (λ=1090 nm) and the laser is not regarded as a suitable tool for ablation based silicon surface texturing. However, we have shown non-ablative texturing of Si surface is possible provided that suitable laser power and dwell time are chosen to produce...
