Beam deflection spectrometry (BDS) is a photothermal spectroscopic technique that offers ultra-sensitivity, high signal-to-noise ratios, and reduced sample preparation requirements. These advantages provide precise assessment of advanced material (AM) properties. This review presents a comprehensive in-depth analysis, thus helping researchers to understand the potential and future perspectives of BDS along with the theory, instrumentation, and application supported by the literature data. The objective of this review is also to present the possibilities of BDS in the characterization of AMs, including organic, inorganic, and hybrid organic–inorganic materials in the form of thin films, coatings, composites, and nanomaterials.","PeriodicalId":17976,"journal":{"name":"Laser Physics","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257176","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}

Multicolor transparency windows appear in the output field under the atom-photon-OPA-phonon-phonon coherent interaction. And the position and width of the transparent port of the output field can be manipulated by properly modifying the different parameters of the subsystem. We also research the slow/fast light effect related to phase and group delay in the probe field.

Furthermore, we propose an alternative and reliable method to study the biospeckle patterns by constructing a color-channel assessment matrix. The proposed approach provides both qualitative and quantitative information of the sample under study, with minimum speckle images and no stringent requirement of correct parameter selection, unlike in the case of GLCM method.

These DWFLs are rarely reported, and this is the first demonstration in these bands using AWGs and ZBLAN fibers with dopants such as praseodymium and thulium. The O-band DWFL was achieved in a praseodymium-doped fluoride fiber laser (PDFFL), and the S-band DWFL was obtained in thulium-doped fluoride fiber lasers (TDFFLs). The dual wavelength with a wavelength spacing of 2.7 nm was generated at operating wavelengths of 1307.4 and 1310.1 nm in the O-band. Meanwhile, the S-band DWFL was generated at operating wavelengths of 1503.6 and 1505.9 nm, with a wavelength spacing of 2.3 nm. The two DWFLs were switched by changing AWG channels within the PDFFL and TDFFL cavities. The O-band and S-band DWFLs were switchable at wavelength spacings of 2.7–22.8 nm and 2.3–20.8 nm, respectively.

Meanwhile, the effect of atmospheric turbulence and the assembly misalignments is also considered. In the paper, the transmission of a PCLGVB through a Cassegrain transmitting antenna is mathematically modeled and the coupling efficiency is numerically calculated. And as the propagation distance increases, the coupling efficiency shows an upward trend. In the meanwhile, the PCB is more resistant to the disruptions introduced by atmospheric turbulence and misalignments. And for the coupling between PCLGVB and the single-mode fiber, as the lateral offset or tilt angle increases, the coupling efficiency remains stable in some intervals, or even appears to grow anomalously, which may provide a new idea for enhancing the coupling efficiency. Compared to the case of perfect alignment, the lateral offset of 0 with a tilt angle of 6.5° has a higher coupling efficiency of 21.35%.","PeriodicalId":17976,"journal":{"name":"Laser Physics","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142184845","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}

This hybrid system integrates the Dzyaloshinsky–Moriya interaction (DMI) and operates under the influence of an external magnetic field. We use local quantum Fisher information (LQFI) for correlation estimation and relative entropy of coherence for coherence measurement in the considered system. Our investigation encompasses various parameters of the hybrid system, the strength of the DMI and the intensity of the external magnetic field. Our findings underscore that elevated temperature compromises both nonclassical correlations and coherence. On the other hand, the robustness of the DMI mitigates the impact of thermal noise on quantum Fisher information correlations and relative entropy of coherence in the hybrid system. Additionally, we inspect the impact of decohering channels-specifically, dephasing, phase flip, and bit- and trit-flip channels-on thermal coherence and quantum correlations. The introduction of various decoherence processes into the hybrid qubit-qutrit system leads to a competition with thermal fluctuations, thereby giving rise to out-of-equilibrium states. Our results indicate that as the decoherence strength parameter (<italic toggle=\"yes\">p</italic>) increases, both LQFI and relative entropy of coherence exhibit similar behaviors in the dephasing and phase flip channels. These resources gradually diminish, eventually disappearing entirely at <italic toggle=\"yes\">p</italic> = 1. In the context of the bit- and trit-flip channels, quantum coherence displays notable distinctions compared to what is observed under dephasing and phase flip channels, revealing that coherence can be preserved if the DMI is strong and the intensity of the external magnetic field is reduced. These findings are important since it is crucial to first understand the decoherence process, arising from the interaction with the environment, and then to find ways to hinder this decoherence in order to avoid the complete loss of the quantum resources necessary to quantum information processing.","PeriodicalId":17976,"journal":{"name":"Laser Physics","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142184847","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}
