Laser ablation in liquid is a scalable nanoparticle production method in areas like catalysis and biomedicine. Different energy dissipation channels, such as absorption by the liquid and scattering at the ablation plume and cavitation bubble, lead to reduced laser energy available for nanoparticle production. Ultrashort pulse durations cause unwanted effects. A study, recently published in in Opto-Electronic Advances, explored pico- to nanosecond pulse duration regimes and found that pulse durations around 1–2 ns enable the most efficient laser ablation in liquid.
