In this paper, we examine the distribution characteristics of the orbital angular momentum of Laguerre–Gaussian (LG) vortex beams in atmospheric and oceanic turbulence, derive analytical expressions for the spiral spectrum of LG vortex beams, and analyze the effects of the wavelengths, transmission paths, and beam intensity on the spectrum within turbulent environments. The findings show that long-wavelength LG vortex beams perform better in turbulent conditions. Blue-green LG vortex beams exhibit significantly enhanced performance in downlink atmospheric transmission compared to uplink transmission. Additionally, greater intensities of atmospheric and oceanic turbulence lead to a more pronounced extension of the spiral spectrum. Oceanic turbulence exerts a greater influence on blue-green LG vortex beams compared to atmospheric turbulence. This paper presents the theoretical foundation for accomplishing two-way blue-green LG vortex beam transmission between the ocean and the atmosphere.</p></div>","PeriodicalId":663,"journal":{"name":"Journal of Russian Laser Research","volume":"45 6","pages":"664 - 675"},"PeriodicalIF":0.8,"publicationDate":"2026-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686598","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 study presents a mathematical model to investigate tissue vaporization during LITT specifically in breast cancer tumor tissue. Building upon established bioheat transfer and Arrhenius damage frameworks, we incorporate effective specific heat (ESH) and enthalpy-based methods to model phase transitions around 100 °C. Breast tissue parameters such as thermal conductivity, water content, perfusion rate, and optical absorption are used to accurately simulate energy deposition and heat propagation. Our simulations provide spatial and temporal patterns of temperature distribution, damage accumulation, and vaporized volume. The model highlights the importance of considering vaporization effects in LITT planning for breast cancer to enhance therapeutic precision and avoid unintended collateral damage.</p></div>","PeriodicalId":663,"journal":{"name":"Journal of Russian Laser Research","volume":"46 4-6","pages":"156 - 179"},"PeriodicalIF":0.8,"publicationDate":"2026-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147985232","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}

In this study, we give a unifying description of the stationary bipartite and tripartite entanglement in a coupled optomechanical ring cavity comprising photon and phonon modes. We numerically analyze the stationary entanglement between the optical mode and each mechanical mode, as well as between the two mechanical modes, using the logarithmic negativity. Our results demonstrate that mechanical entanglement between the two mechanical modes is highly dependent on the optical normalized detuning and the mechanical coupling strength, with entanglement maximized within specific detuning intervals and increased coupling broadening the effective range. Furthermore, we study the entanglement’s sensitivity to temperature, noting that higher coupling strengths can sustain entanglement at elevated temperatures. The study also reveals that the entanglement between the mechanical mode and the optical mode is enhanced with increasing laser power, but is similarly susceptible to thermal noise. Additionally, we explore tripartite entanglement through the minimum residual contangle, highlighting its dependence on detuning, temperature, and laser power. Our findings underscore the importance of parameter control in optimizing entanglement for quantum information processing applications.</p></div>","PeriodicalId":663,"journal":{"name":"Journal of Russian Laser Research","volume":"46 4-6","pages":"100 - 113"},"PeriodicalIF":0.8,"publicationDate":"2026-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147985239","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}

But they usually depend on one modality and cannot extract information from others. LiDAR and camera multimodal fusion combines data from two sources, greatly increasing detection precision. This paper proposes a new network called the Convergent Attention-Enhanced Camera-LiDAR Object Candidates System (CAECs). It is a decision-level fusion architecture for target detection. First, the CAECs network uses an advanced candidate encoding mechanism. This mechanism sifts through and saves prime candidates from both 2D and 3D detectors. It forms a comprehensive feature tensor and avoids missing crucial detections. Second, we use AgileSightNet to improve feature relevance and strengthen important data. AgileSightNet includes layered channel fusion and an attention scheme. The tests on the KITTI benchmark show that our method performs better at detecting pedestrians and cyclists. It improves accuracy by 6.43% and 6.26% compared to the existing 3D multimodal networks. Compared to single-modal 3D networks, our method improves detection accuracy by 13.03% and 5.97%.

According to the second quantization formalism, the location and direction of the electric dipole are the main factors governing the process of suppression or enhancement. The stationary approach assumes that the electric dipole has a fixed direction; hence, spontaneous emission is presented in three perpendicular Cartesian coordinates. This approach can be considered valid when certain conditions are available, such as a short waveguide length and high atomic velocity. It explicitly ignores the fact that the electric dipole vector is a dynamic variable. On the other hand, the dynamic approach presents the total spontaneous emission as a directional sum of possible coordinates, which improves the product and makes it closer to experimental results. This approach only requires pre-excitation by an external light mode in order to control the expected directions. The single-mode waveguide offers a radical solution that completely avoids the electric dipole orientation obstacle. Its production has been made possible by advances in micro-fabrication technology.</p></div>","PeriodicalId":663,"journal":{"name":"Journal of Russian Laser Research","volume":"46 4-6","pages":"114 - 125"},"PeriodicalIF":0.8,"publicationDate":"2025-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147985241","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}
