Here, we investigate how the irregular roughness of 1D metasurfaces influences the disruption of structural symmetry and impacts the excitation of quasi-BIC. First, random roughness is introduced on the sidewalls of a 1D grating constituting a metasurface. Then, the excited resonance of a rough metasurface is compared with the quasi-BIC of a metasurface possessing regular asymmetry with a flat sidewall to verify that the excited resonance is due to the quasi-BIC. Furthermore, the influence of degree of roughness is examined by analyzing the resonance wavelength and the excited field intensity. As the roughness increases, the resonance wavelength distribution broadens toward longer wavelengths, and the largest field intensity increases, although lower intensities dominate overall. Second, the distribution of resonance wavelengths and the range of maximum field intensities are analyzed with an increase in the number of gratings with independent rough profiles in a super-cell. As additional gratings are incorporated into the super-cell, the resonance wavelength distribution converges to the true BIC wavelength. At the same time, the range of maximum field intensity gradually decreases. Last, we investigate rough metasurfaces covered with a homogeneous high-refractive-index layer and confirm the excitation of two quasi-BICs having opposite parities.</div></div>","PeriodicalId":19511,"journal":{"name":"Optics and Laser Technology","volume":"189 ","pages":"Article 113070"},"PeriodicalIF":4.6,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

In this paper, we propose an efficient approach to detect wide-range OAM modes using a mode transformer for the Laguerre-Gaussian (LG) beams. The mode transformer includes a phase mask (P1) that consists of three parts: the transformation term, the fan-out term, and the inverse term. And a phase corrector (P2). The fan-out mapper creates multiple copies of the transformed beams. After applying the phase mask, optical geometric transformations yield the optical matrix. Following phase correction, the light spots that form at the focal plane are identified by a CCD. We further extend the detection range by introducing an appropriate inverse phase to the P1 mask. Simulation tests have demonstrated outstanding detection performance, highlighting the potential of our proposed method to enhance the detection efficiency of multiplexed OAM beams.</div></div>","PeriodicalId":19511,"journal":{"name":"Optics and Laser Technology","volume":"189 ","pages":"Article 113074"},"PeriodicalIF":4.6,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

LSP without coating (LSPwC) has emerged as an attractive alternative that eliminates the need for protective coatings, simplifies processing steps, and reduces costs. However, the comparative advantages of LSPwC and conventional mechanical shot peening (SP) for titanium alloy surface enhancement remain unclear. In this study, the effects of SP and LSPwC on the residual stress distribution and deformation characteristics of Ti60 alloy are systematically compared. The results reveal that although SP generates a higher maximum compressive residual stress (−549 MPa) than LSPwC (−392 MPa), it produces a shallower compressive layer (280 μm vs. 370 μm). Analysis of the full-width at half maximum (FWHM) indicates distinct stress profiles: SP induces the most severe elastoplastic deformation at ∼50 μm depth, accompanied by a non-monotonic stress distribution, whereas LSPwC primarily affects the outermost surface. Moreover, SP provides stronger surface strengthening within ∼150 μm depth, while LSPwC—due to its lower energy input—achieves a deeper compressive residual stress layer. These findings enhance the understanding of SP and LSPwC mechanisms, providing critical insights for optimizing surface processes in industrial applications.</div></div>","PeriodicalId":19511,"journal":{"name":"Optics and Laser Technology","volume":"189 ","pages":"Article 113100"},"PeriodicalIF":4.6,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143902585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
