We introduce a quasi-three-dimensional analysis method that incorporates iterative electro-optical-thermal multimodal coupling. This method account for the effects of temperature on both electrical and optical performance, as well as the impact of electro-optical coupling on the heat generation. Compared to a typical 808 nm single-emitter device with a cavity length of 4 mm and a ridge-waveguide width of 105 μm, the device configuration with a 100 μm NIW demonstrates superior performance. Specifically, the front facet temperature drops by 5.4 °C, and the bandgap shrinkage is reduced by 43 %, reaching a value of 2.1 meV under a continuous wave condition at 10.8 A and room temperature.

In particular, the application of the garnet-type ceramic solid electrolyte lithium lanthanum zirconium oxide (LLZO) is receiving growing attention due to its high ionic conductivity and exceptional stability towards lithium metal (Li). However, LLZO reacts with water and carbon dioxide in the ambient air, forming an insulating layer of lithium carbonate on the surface of the garnet-type solid electrolyte. This insulating layer leads to a reduction in the wettability of LLZO by Li and in turn, increases the Li/LLZO interfacial resistance. This study explores ultrashort pulsed laser processing under an argon atmosphere as an effective method for removing Li<sub>2</sub>CO<sub>3</sub> while minimizing the thermal input and preserving the structural integrity of the LLZO. Energy-dispersive X-ray spectroscopy revealed a distinct decrease in carbon content after the laser-based surface treatment. Furthermore, electrochemical impedance spectroscopy of symmetrical Li/LLZO/Li cells indicated that the laser-based removal of Li<sub>2</sub>CO<sub>3</sub> could reduce the total area-specific resistance by up to 94 %. These results demonstrate that the laser-based surface treatment is a promising approach for removing surface contaminations from the garnet-type solid electrolyte. Moreover, the findings of this study contribute to the ongoing efforts to extend the lifespan of next-generation batteries by improving the interfacial stability.</div></div>","PeriodicalId":19511,"journal":{"name":"Optics and Laser Technology","volume":"189 ","pages":"Article 113118"},"PeriodicalIF":4.6,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143928881","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}

The optimal structural parameters were the concavity region width of 400 µm, protrusion region width of 150 µm, and scanning times of 7. Under the above laser processing parameters and structural parameters, we could obtain superhydrophobic surfaces with anisotropy.
