By amplifying the cascaded random Raman fiber laser (RRFL) oscillator and ytterbium fiber laser oscillator, we present the first, to the best of our knowledge, demonstration of a 10-kW-level high-spectral-purity all-fiber ytterbium–Raman fiber ampl

Abstract Background Early identification of patients at risk of osteopenia is an essential step in reducing the population at risk for fractures. We aimed to develop and validate a prediction model for osteopenia in Chinese middle-aged and elderly me

We report on a 13.2 W, 474 fs, 31.12 MHz, all-polarization-maintaining (PM), 1560 nm fiber laser system based on the chirped-pulse amplification (CPA). The home-built seed laser with the nonlinear amplified loop mirror (NALM) can deliver two trains o

We herein develop a selective phosphoranation of alkynes with phosphonium cation, which directs a concise approach to isoquinolines from unactivated alkyne and nitrile feedstocks in a single step. Mechanistic studies suggest that the annulation react

Hyperspectal target tracking is aimed at taking advantage of the spectral and spatial information in the target tracking. However, due to the limited training samples, the existing hyperspectral target trackers cannot exploit semantic information of
