Repetition rate-dependent absorbance measurements of synthetic fused silica at 193-nm irradiation are performed in the range of 50–1 000 Hz with an ArF laser calorimeter. The "apparent" single- and twophoton absorption coefficients are determined by mea
Metal halide perovskite materials have been widely studied recently due to their excellent optoelectronic properties. Among these materials, organic-inorganic hybrid perovskites have attracted much attention because of their relatively soft framework, whi
Two frequency selective surface (FSS) configurations with flat topped passband are presented in this paper. One configuration is single layer FSS with lambda/4 thickness dielectric loaded on both sides, and the other is double layers FSS. Based on the mod
We study ionic structure of KNO3–NaNO2 melts under air atmosphere by using Raman spectroscopy. Molar fraction of NO3- and NO2- is obtained and thermal stability of this kind of melts system is then analyzed. The results show that when the temperature is i
Laser communication using photons should consider not only the transmission environment’s effects, but also the performance of the single-photon detector used and the photon number distribution. Photon communication based on the superconducting nanowire s
