It was shown that the ablation of meso- and microporous silicon layers by picosecond laser pulses in water and ethanol leads to the formation of nanosilicon suspensions with a diameter of less than 100 nm. It has been demonstrated that the use of porous silicon allows to reduce the thresholds of laser ablation and increase the concentration of particles in suspensions in comparison with the case of crystalline silicon ablation.
