There exists an increasing demand of industrial-scale production of high-purity ligand-free nanoparticles due to
the continuous development of biomedicine, catalysis, and energy applications. In this contribution, a simultaneous spatial and temporal focusing (SSTF) setup is first proposed for increasing nanoparticle productivity of the
eco-friendly pulsed laser ablation in liquids (PLAL) technique. In spite of the fact that femtosecond pulses have
proved to achieve higher ablation rates in air than picosecond pulses, in PLAL this is reversed due to the nonlinear
energy losses in the liquid. However, thanks to the incorporation of SSTF, the energy delivered to the target is
increased up to 70%, which leads to a nanoparticle production increase of a 2.4 factor. This breaks a barrier
toward the employment of femtosecond lasers in high-efficiency PLAL. [-]
