A set of phosphate glasses with different amounts of Al_(2)O_(3), Na_(2)O, La_(2)O_(3) and AlF_(3) contents were prepared to search for a phosphate glass which is suitable for ion-exchange process. Based on chemical durability test results and spectroscop
Introducing the finite difference time domain method and perfect match layer absorbing boundary condition, the electro-tunable localized modes in two-dimensional (2D) nematic-liquid-crystal photonic crystal with a point defect (1PD2D-NLCPC) are investigat
The noise origin of attenuation system is explored by analyzing the wedged plate attenuator based on Fresnel transmission through two pairs of wedged plates. Multiple reflections between two surfaces of a pair of wedged plates introduce fluctuating error
Interpreting the biochemical specificity of spinal cord tissue is the essential requirement for understanding the biochemical mechanisms during spinal-cord-related pathological course. In this work, a longitudinal study was implemented to reveal a precise
Quasi-parametric chirped-pulse amplification (QPCPA) can improve the signal amplification efficiency and stability by inhibiting the back-conversion, in which the idler absorption plays a critical role. This Letter theoretically studies the impacts of idl
