According to the principle of blackbody radiation, the experimental exploration of high temperature optical fiber temperature sensor was carried out. The high temperature resistant calcium tungstate material was used as the blackbody radiation material to be made the optical fiber radiation probe. Optical power meter was used to measure the optical power of 980nm wavelength in every 10°C in the range of 150-800°C. The fourth-order polynomial was used to fit the relationship between the radiation optical power and the temperature, and the fourth-order optical power and temperature expression with a fitting degree of 0.99953 was obtained. The temperature measurement accuracy was within 1 % in the temperature range of 400-800 ℃. © 2024 SPIE.

The generation of terahertz(THz) waves by focusing a femtosecond pulsed laser beam at a distance is able to overcome the strong absorption properties of air and has rapidly attracted the attention of industry. However, the poor directionality of the THz wave radiation generated by this method is not conducive to THz wave applications. By controlling the morphology of the ultrafast laser-excited plasma filament and its electron density distribution through coherent beam combining technology, we achieve direct THz beam shaping and are able to obtain THz wave radiation of Gaussian or arbitrary transverse distribution. The novel experimental approach proposed in this paper opens up the research field of direct THz wave shaping using plasma. Moreover, it innovates multi-parameter convergence algorithms and, by doing so, has the potential to find beam patterns with higher energy conversion efficiency and break the energy limit of THz waves emitted by lasers at high power.

Remote response modes on the paced excitable C. elegans network

Physical Review Research 2024年第3期6卷 033014-033014页

In paced excitable systems, a traditional viewpoint on signal transmission is that an excitable pacing signal should propagate from the source to its excited neighbors in a sequential rule, which is known as the normal sequential response mode (SRM). However, in our present paper, by extensively exploring the response modes emerged on the paced excitable C. elegans network, we found that, besides the normal SRM, a response mode that breaks the sequence rule and contains isolated excited clusters or even isolated excited nodes on the propagation path of the response structure can be detected. Such remote response nodes and clusters are excited discontinuously from the source node, forming the phenomenon of the remote response mode (RRM). An effective-driving analysis approach (EDAA) is proposed to theoretically study the mechanism of the RRM, based on which key role played by the excited nodes possessing nonexcited upstream driving neighbors is confirmed in the formation of the RRM. We further verify the applicability and the universality of the EDAA in identifying the RRM on general paced excitable networks. These contributions are expected to shed light on the study of complex response modes in paced excitable systems and to have great impact in related topics.
