Laser-induced nucleation of supersaturated aqueous sodium bromide

This dataset comprises original images and videos collected during experiments on the nucleation and crystal growth from supersaturated aqueous solutions of sodium bromide.
Different methods were used to induce nucleation: mechanical shock-induced nucleation, nucleation by ultrasound (sonocrystallization), non-photochemical laser-induced nucleation (NPLIN) and laser-trapping nucleation. The most stable crystal form at room temperature is known to be sodium bromide dihydrate (DH) and this form was favoured (> 95%) through spontaneous nucleation or mechanical shock. Sonocrystallization favoured DH crystals (74%). Remarkably both laser-induced nucleation methods showed a strong preference (> 90%) for anhydrous (AH) crystals.
