WebbA novel tunable fiber ring laser configuration with a combination of bidirectional Raman amplification and dual erbium-doped fiber (EDF) amplification is proposed for realizing high optical signal-to-noise ratio (SNR), long-distance, quasi-distributed fiber Bragg grating (FBG) sensing systems with large capacities and low cost. The hybrid Raman-EDF … WebbRahmen Proteinuria is a major marker of chronic kidney disease (CKD) progression and the preventer of cardiovascular mortality. The fastest development of renal failure is expected in the patients who have taller level of proteinuria however, some patients maybe have slow decline of renal function though lower level of urinary protein excretions. The different … song the storm is almost gone

Introduction Fiber lasers with effective modal control to achieve specific high-order modes (HOMs) output have attracted numerous attention in the past few decades, thanks to their unique polarization, WebbWe experimentally explore the relation between spectral linewidth and RIN transfer in half-open cavity random distributed feedback Raman lasers, demonstrating for the first time the possibility of adjusting the pump-to-signal RIN transfer intensity and cut-off frequency by using spectral filtering in the reflector section.
