    • openAccess   Dynamic freeform diffractive lens 

      Mendoza-Yero, Omel Optica Publishing Group (2023-03-31)
      In the framework of the scalar theory of diffraction a surface-pixeled convergent lens for arbitrary amplitude and phase modulation along the depth of focus is introduced. This complex diffractive lens is computer-generated ...

    • openAccess   Unveiling fundamentals of multi-beam pulsed laser ablation in liquids toward scaling up nanoparticle production 

      Gatsa, Oleksandr; Tahir, Shabbir; Flimelová, Miroslava; Riahi, Farbod; Doñate Buendía, Carlos; Gökce, Bilal; Bulgakov, Alexander MDPI (2024-02-16)
      Pulsed laser ablation in liquids (PLAL) is a versatile technique to produce high-purity colloidal nanoparticles. Despite considerable recent progress in increasing the productivity of the technique, there is still significant ...
