Graphical illustrations show that the solved NLPDE admits both compressive and rarefactive solitary solution depending on the velocity of the solitary structure. 3-D representation of compressive and rarefactive solitary structuresd appear as the spokes like structures (dark and bright, respectively) which are wider at the base and become narrower as the radial distance increases. This observation further supports the hypothesis that nonlinear drift waves may indeed correspond to the spokes observed in Saturn’s B-ring. It is noted that bright and dark spokes exhibit distinct behaviors in response to variations in the plasma parameters. By applying plasma parameters typical of those found in Saturn’s B-ring, it is demonstrated that the theoretically predicted spatiotemporal scale lengths align closely with the observations of the spokes made by various space missions and the Hubble Space Telescope (HST).</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"70 ","pages":"Article 108149"},"PeriodicalIF":4.4,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143420690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

This unique structural configuration facilitates multiple bidirectional RS interactions, providing sufficient random distributed feedback (R-DFB) for the laser system. Initially, random laser (RL) outputs at 1560 nm were achieved using both ring-cavity and single-ring sub-cavity structures.

Subsequently, the laser system was upgraded to a dual-ring sub-cavity configuration, and its output performance was re-evaluated. The experimental results show that the wavelength and output power fluctuations are reduced to 0.28 nm and 0.26 dB, respectively. Benefiting from the enhanced R-DFB and superior filtering properties of the dual-ring sub-cavity, the frequency noise of the lasing output decreased significantly to 0.03 Hz/√Hz, the lowest value reported to date.
