All‐Inorganic TiO 2 Nanoparticle‐Based Metalenses Manufactured by Direct Nanoimprint Lithography for High Energy Applications: Femtosecond Laser‐Induced Damage Threshold Testing (Advanced Optical Materials 2/2026)
Source abstract
Abstract
Meta Optics High optical stability of directly nanoimprinted metalens arrays was demonstrated using femtosecond high-energy laser pulses with an exposure time over 3 hours. Unlike an earlier failure of TiO2 nanoparticle-polymer composite metalenses at a much lower fluence (< 8 mJ/cm2), the all-inorganic TiO2 metalenses remained intact (> 64 mJ/cm2) and maintained high focusing efficiency. More details can be found in the Research Article by James J. Watkins and co-workers (DOI: 10.1002/adom.202501769).
