The size, morphology, and optical properties of the synthesized AuNPs were determined using transmission electron microscopy (TEM) and UV-Vis spectroscopy. TEM analysis confirmed the formation of AuNPs that are mainly spherical, with particle size increasing as the number of laser pulses increases (250, 500 and 750 pulses) due to coalescence. The photocatalytic activity of the AuNPs was studied by monitoring the degradation of the MO dye under infrared (IR) irradiation for 60 min. The degradation efficiency was recalculated by <i>η</i>=(<span>(:{A}_{0}-{A}_{t})</span>)/<i>A₀</i>×100, and it was observed that the efficiency increases with the irradiation time for all the tested samples. Degradation efficiencies of 64%, 58% and 48% were obtained after 60 min of IR exposure for AuNPs synthesized with 250, 500 and 750 pulses, respectively, with the maximum value of 64% being observed for the 250-pulse sample. This study also reports the potential of PLAL-synthesized AuNPs to be used as effective and eco-friendly catalysts for the removal of organic pollutants such as MO dye from wastewater. Moreover, it highlights the strong dependence of the photocatalytic efficiency on the preparation conditions of the nanoparticles and on the irradiation time.</p></div>","PeriodicalId":722,"journal":{"name":"Optical Review","volume":"33 5","pages":"740 - 749"},"PeriodicalIF":1.0,"publicationDate":"2026-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149235921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this system suffers from reduced light utilization efficiency and specular reflection from the beam splitter because the image-forming light passes through the beam splitter multiple times. In this study, we propose two polarization-modulated optical configurations for convex-mirror-based AIRR. The first configuration employs a reflective polarizer and two λ/4 retarder films to improve the apparent brightness of enlarged aerial images. The second configuration employs a λ/4 retarder film and an additional linear polarizer placed in front of the observer to suppress specular reflection from the beam splitter. Experimental results show that the convex-mirror-based p-AIRR system maintained the floating-distance extension and image magnification of the conventional convex-mirror-based AIRR system, achieving a floating distance of 830 mm and an image magnification of 3.4× at a light-source-to-reflective-polarizer distance of 500 mm. In addition, the observation-side polarization-control configuration visually suppressed beam-splitter-originated specular reflection while preserving the aerial image.

To address these issues, this paper proposes a metasurface solution based on dual-focal-plane holographic imaging. Based on angular spectrum diffraction theory (ASM), this metasurface is capable of achieving holographic imaging in three distinct channels when the incident light is polarized along the x-polarized, the y-polarized, and at 45° (or its orthogonal 135° polarization). By introducing the rotation angle of the nanocolumns, polarization multiplexing is combined with axial focusing capability to further switch the combination of linear polarization states at the input and output, thereby obtaining a total of twelve switchable polarization-spatial joint display channels at the two preset focal planes.
