This study proposes a decoupling method and its technical path for the optical force- and thermal effect-induced coupling elastic wave based on the frequency analysis of an analytical model of coupling elastic waves. The decoupling method can effectively identify the optical force-induced elastic wave. A multipulse enhancement of the amplitude of optical force-induced elastic waves is also theoretically proven based on the time domain analysis of the analytical model. To verify the method, a measurement platform is built for coupling elastic waves. The experimental results show that as the single pulse energy increases, the amplitude of the coupling elastic waves experiences nonlinear growth, which is mainly caused by the thermal effect. At a single pulse energy of 3.8 mJ, the average amplitude of the coupling elastic waves is 1.02 nm, consistent with the theoretical value of thermoelastic waves of 1.14 nm. By extracting high-frequency vibration, optical force-induced elastic waves are successfully decoupled, with the amplitude increasing linearly with the single pulse energy. At a single pulse energy of 3.8 mJ, the average amplitude is 294.9 pm, showing an enhancement compared to the theoretical value. The significance of this study lies filling a gap in the existing theoretical framework and has significant value in the application of optical force on a macroscopic scale.</div></div>","PeriodicalId":19586,"journal":{"name":"Optics Communications","volume":"575 ","pages":"Article 131261"},"PeriodicalIF":2.2,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142654587","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}

Current RSs commonly rely on full-pixel speckles, but this study demonstrates that localized speckles also convey global spectral information. Experimental results show that an integrating sphere's local speckles can improve spectral measurement speed by 35 times with minimal loss in accuracy compared to full-pixel speckles of a multimode fiber (MMF). The study investigates the influence of the position and size of local speckles on RSs.

In this study, we controlled the THz refractive index and extinction coefficient of the 3D printing resin by UV exposure doses during the printing process.

The refractive index and extinction coefficient were changed from 1.65 to 1.80, and from 0.04 to 0.12, respectively, with increasing UV doses from 1 mJ/cm<sup>2</sup>, which allows resin to solidify and become printable, to 100 mJ/cm<sup>2</sup>, where the optical changes become almost saturated.
