Abstract

Laser-induced ablation in liquids (LAL) is widely used for nanoparticle generation, yet its underlying mechanisms are not completely understood. We investigate interactions between shockwave, cavitation bubble and target material by multi exposure imaging with high temporal and spatial resolution. Our home-built Yb-based master oscillator fiber amplifier system delivers 170 ps pulses at 2 µJ and tunable burst rates up to 5 GHz, ideal for capturing transient events. Speckle-free imaging is achieved using a fiber-based rapid optical mode mixing approach combining spectral broadening with optical delay and spatial mode mixing of frequency-doubled 532 nm pulses.
