The influence of applying the additional continuous laser on the synthesis of silicon-based nanoparticles by picosecond laser ablation in liquid

Silicon-based nanoparticles are synthesized by picosecond laser ablation in liquid using silicon single-crystal plates as targets. We demonstrated that applying the additional continuous laser immediately prior to and during the ablation changed the size distribution and oxygen content of the nanoparticles produced. This opens up the possibility of using the continuous laser as a simple tool for tailoring nanoparticle properties.
