Laser-induced crystallization is expected to enable the spatial and temporal control of nucleation and crystal growth. In this study, urea crystals in a supersaturated solution were irradiated with femtosecond laser pulses, which induced secondary nucleation through the dispersion of small crystal fragments. This secondary nucleation process was observed using a Mach-Zehnder interferometer. Refractive index distributions reconstructed from transmission interferograms indicated local solute concentration changes associated with secondary nucleation.
