The influence of process parameters on cladding quality and geometry, and the impact of h-BN contents (2 wt% and 5 wt%) on the microstructure and mechanical properties of the coatings were studied. Optimal process parameters for 316L/5wt%BN coatings were identified: a powder feeding rate of 3–4 rpm, a laser power of 2200–2400 W, a scanning speed of 4–5 mm/s, and an overlapping rate of 40 %. Microstructural analysis showed a smooth surface without cracks or pores. X-ray diffraction revealed intermetallic compounds such as CrB, CrN, FeN, BN, and γ-(Fe, Ni). The inclusion of h-BN nanoparticles enhanced grain refinement, significantly increasing microhardness. Coatings with 5 wt% h-BN achieved an average microhardness of 438.8 HV10, 2.5 times higher than the substrate and the 316L stainless steel. Additionally, h-BN reduced friction coefficients, leading to substantial wear reduction. The 316L/5 wt% h-BN sample experienced only 4.2 mg of wear, 45.16 % of the substrate’s wear. These findings highlight the beneficial effects of h-BN nanoparticles on 316L stainless steel coatings, enhancing wear resistance, hardness, and overall performance.","PeriodicalId":19597,"journal":{"name":"Optics & Laser Technology","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141933933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, traditional mechanical surface treatment methods are challenging to apply to CFRP because of their anisotropic and nonhomogeneous properties. Femtosecond laser offers unique advantages for surface treatment, as it allows processing with very low thermal load due to the extremely short interaction time. This study investigates the effect of different surface structures resulting from surface treatment using a femtosecond laser on adhesive properties of CFRP. The experimental results show that: 1) beam shaping can be realized by using the plano-convex cylindrical mirror, which improves the quality of laser processing and greatly improves processing efficiency. It only takes 20 s to complete the laser processing of a 1 cm*1 cm area, which increases the work efficiency by 49 times. 2) pre-bonding surface treatment significantly enhances the tensile shear strength of the single lap joint, and the shear strength of samples with low spatial frequency LIPSS (LSFL) (14.57 ± 1.58 MPa) is 2.96 times higher than that of the untreated sample (US) (4.92 ± 1.34 MPa). 3) LSFL structure exhibits the best results, because the surface of CFRP with LSFL exhibits a relatively higher surface polarity and surface energy. This study provides an efficient, high-precision, and low-damage surface treatment method for preparing CFRP for adhesive bonding, which may promote the application of femtosecond laser technology in difficult-to-process composite materials and provide new methods and technical support for its application in aerospace, vehicle manufacturing, and other fields.","PeriodicalId":19597,"journal":{"name":"Optics & Laser Technology","volume":"86 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141933934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in the noisy intermediate-scale quantum (NISQ) era, quantum computers as servers only control limited number of qubits and are not powerful enough. In addition, each of current BQC models is usually suitable for only one type of users. Therefore, this paper offers a flexible BQC ( for short) model for two types of users with different quantum capabilities where any one of two types of users can complete BQC tasks with the help of the other type of users and quantum servers. To be more specific, we propose two protocols by using the given model. In the first protocol, one user Alice only with the ability to prepare single-qubit states can realize BQC tasks by cooperating with another user Bob who is just capable of performing single-qubit measurements and a quantum server Charlie. Similarly in the second one, Bob can realize BQC tasks by cooperating with Alice and Charlie. In both protocols, the server Charlie only requires a quantum register of small size and performing CZ gates and thus it is unnecessary to be universal and may be less difficult to realize in the short run. Furthermore, both proposed protocols are verifiable, namely that the user can detect whether the server is honest. Finally, examples of the proposed protocols for implementing Deutsch’s algorithms are simulated through Qiskit framework to show their feasibility and correctness.","PeriodicalId":19597,"journal":{"name":"Optics & Laser Technology","volume":"78 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141933936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this report, we theoretically show simultaneous generation of high- surface lattice resonances (SLRs) and quasi-bound states in the continuum (quasi-BICs) in single dielectric metasurfaces composed of symmetry-broken unit cells of GaP nanorods surrounded by silica glass. Quite interestingly, there are quasi-BIC with double asymmetry parameters and also the resonance with duality between SLR and symmetry breaking-induced quasi-BIC, in addition to simple SLRs and quasi-BICs. For different polarizations of incident waves, one can obtain multiple high- SLRs and quasi-BICs, which can be used for efficient generation of coherent radiations in the range from visible to mid-infrared by second-harmonic generation (SHG), sum-frequency generation (SFG), and difference-frequency generation (DFG). The numerical results show that mid-infrared radiation at around 14 μm can be directly generated from the dielectric metasurfaces by DFG with an efficiency of about 1.4 × 10 % for pump intensities of 20 MW/cm by pumping at the resonant wavelengths of SLR and quasi-BIC. Besides efficient frequency conversions, coexisting high- SLRs and quasi-BICs in dielectric metasurfaces can also be employed for various photonic applications such as sensitive sensing.","PeriodicalId":19597,"journal":{"name":"Optics & Laser Technology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141933969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we use a single-hole dual-core fiber (SHDCF) based Fabry–Pérot interferometer (FPI) to simultaneously detect the refractive index and temperature of solution, with high sensitivity enhanced by the vernier effect. The inlets and outlets are built by splicing C-shaped fiber and fiber capillary between SHDCF. A detection region inside the microscopic hole of SHDCF obtained after splicing is constructed. Our method offers high sensitivities of 6851.89 nm/RIU and 0.493 nm/℃ for RI and temperature in a liquid solution, respectively. Notably, the cross-sensitivity of RI and temperature can be eliminated by constructing a transmission matrix.

The next step towards a high repetition rate generation of stable and high-quality electron beams also requires to measure and monitor in real time and in single-shot the laser parameters, which may be a tough task for fs high-power laser systems. In this article, conducted at the LAPLACIAN LPA facility, we propose a simple way to measure all important laser parameters in real time without disturbing the main beam delivered on target, while ensuring to thwart intrinsic issues such as aberrations and dispersion. The beam leakage from the last mirror, just after the focusing optics, is used and sent towards a dedicated setup where, mainly, the energy, the pulse duration, the FF and NF profile (implying beam pointing and size), the spectrum and the M2 are measured. A prismatic blade has been designed to compensate aberrations introduced during the leakage process, and also chirped mirrors are used to compensate the dispersion. This real-time laser metrology system is fully operational to monitor what is reaching the target, and it should help in the future to have a better understanding on the electron beam generation and its instabilities.","PeriodicalId":19597,"journal":{"name":"Optics & Laser Technology","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141933973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
