Laser-fragmentation-in-liquid device and laser-fragmentation-in-liquid apparatus

Abstract

An LFL device includes a device body and an ultrasound applier. The ultrasound applier is mounted on the device body. The device body includes an internal flow path that allows passage of metal particle dispersion in which metal microparticles are dispersed. The ultrasound applier applies ultrasound to the metal particle dispersion that is flowing through the internal flow path. An outer surface of the device body is provided with a light transmitting part that transmits a laser beam. The laser beam is irradiated to the metal particle dispersion in the internal flow path to which ultrasound has been applied by the ultrasound applier. This improves uniformity of irradiation of metal microparticles with laser beams.
