We derive the conditional position probability distribution of probe absorption, elucidating how variations in phase and detuning can manipulate spatial localization patterns. Distinct absorption patterns are observed, with a maximum detection probability of 25% in defined subspaces. Further analysis reveals that adjusting the relative phase of the applied fields leads to significant reconfigurations of the absorption maxima, enhancing spatial confinement and predictability of the quantum system’s position. Additionally, we explore the impact of detuning, demonstrating that manipulating detuning narrows absorption volumes, reduces positional uncertainty, and achieves up to 100% detection probability in specific regions. These findings underscore the critical role of quantum interference effects arising from standing-wave fields, which generate spatially varying Rabi frequencies and dictate the modulation of probe absorption. The results provide valuable insights into the control of light-matter interactions, with implications for quantum information processing and precision measurement applications.</p></div>","PeriodicalId":474,"journal":{"name":"Applied Physics B","volume":"131 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143740822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

The damage progresses through four stages: lens damage, point damage, line damage, and stress damage. Results show that continuous laser exposure leads to gradual expansion of the damaged area over time, while narrow-pulse multi-pulse lasers cause more severe damage to CMOS. Lens and point damage are mainly caused by thermal ablation, which reduces the CMOS light source’s focusing efficiency and damages the MOS structure. Line and stress damage result from a combination of thermal ablation and thermal stress. Damage to the metal wiring layer can cause entire rows or columns of pixels to fail, while the insulation layer may rupture due to thermal stress expansion, ultimately leading to CMOS function failure during imaging.</p></div>","PeriodicalId":474,"journal":{"name":"Applied Physics B","volume":"131 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Calculated dispersion relations, propagation lengths of plasmon modes in the system are presented. This allows us to characterize and categorize the modes into two groups: Ferrel-Berreman modes and surface plasmon polaritons.

Luminescence thermometry demonstrates significant potential for engine testing applications. However, in engine combustion environments, the luminescence imaging thermometry of hot-end components wrapped in high-temperature, high-pressure, and high-speed combustion gas flow still faces challenges such as coating reliability and flame interference. Therefore, this paper conducted a study on the measurements of blade temperature distribution in engine combustion environments using two-color luminescence imaging thermometry based on atmospheric-plasma-sprayed YAG:Dy (Dysprosium-doped yttrium aluminum garnet) coating. YAG:Dy coatings were prepared on a metal substrate using APS (Atmospheric plasma spray) technology. By carrying out systematic emission spectroscopy experiments at varying temperatures (300–1273 K) and oxygen concentrations (0% (N₂) and 21% (air)), we comparatively investigated the temperature and oxygen concentration dependence of the luminescence intensity ratio (LIR) for both YAG:Dy coatings and powder samples. The experimental results revealed distinct thermometric performance characteristics between the two sample types. Notably, the dense APS YAG:Dy coating exhibited stable luminescence intensity and LIR values across varying oxygen concentrations, demonstrating its suitability for temperature measurement in environments with fluctuating oxygen concentrations, such as combustion and catalytic reactions. Then, the optimal measurement windows for luminescence intensity ratio measurements were determined through spectral analysis of jet fuel combustion flames. A two-color luminescence imaging thermometry system was established based on pulse excitation and detection coaxial optical path, single ICCD (Intensified charge-coupled device) coupled dual spectrum synchronous imaging. The calibration of the imaging thermometry system and the temperature calibration of the luminescence intensity ratio of APS YAG:Dy coating in the range of 573–1273 K were carried out. Experimental measurements of blade temperature distribution were performed under steady-state conditions in an engine combustor test rig (inlet total pressure ~ 2 atm, exhaust total temperature 1000–1170 K). The maximum measured temperature of the blade was about 1163.6 K, and the minimum relative standard deviation range of temperature was 0.30% ~ 0.48%. The reliability and thermometric performance of the APS YAG:Dy luminescent coating were validated under high-speed, high-temperature gas flow conditions, confirming the efficacy of the developed two-color luminescence imaging thermometry system. This research provides valuable insights for implementing luminescence imaging thermometry in engine combustion environments, particularly for dynamic targets and transient processes.</p></div>","PeriodicalId":474,"journal":{"name":"Applied Physics B","volume":"131 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00340-025-08450-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is demonstrated that the reflected GH shift is sensitively dependent upon the SGC effect. The controllable GH shift originates from the competition between the internal damping and radiation damping. Furthermore, in the presence of SGC, the magnitude, sign, and position of the GH shift can be effectively controlled via adjusting the intensity and detuning of the trigger field.

Proximate analysis has been performed to specify the quality of the different coal samples and has been correlated with the results obtained by the LIBS technique.
