Dynamic Multi‐Focus 3D Laser Nanoprinting Based on Two‐Step Absorption and Computational Holography
Laser &Photonics Reviews, Volume 19, Issue 12, June 18, 2025.Low single‐focus laser powers in two‐step‐absorption 3D laser nanoprinting make parallelization efforts a viable route to increase print speeds while still relying on compact continuous‐wave lasers. Herein, an established two‐step‐absorption photoresist system with computational holography based on a digital micromirror device is combined in order to ...

Advanced Materials, Volume 37, Issue 19, May 12, 2025.This study introduces a multimodal nonlinear microscopy approach using upconverting nanoparticles (UCNPs) under continuous‐wave excitation. The UCNPs exhibit high‐order nonlinear optical responses, enabling deep‐tissue 3D imaging, video‐rate wide‐field imaging, and depth‐selective photomodulation.

Healthcare Technology Letters, Volume 12, Issue 1, January/December 2025.The main idea of the present work is the using of 3D scan to acquire directly in the surgical room the final shape of the nose and to show the surgeon the differences respect to the planning in an intuitive way. This is achieved by using projected augmented reality to project false colours directly onto the patient's face.
