WebMar 27, 2024 · Abstract: We demonstrate an ultra-narrow-linewidth Brillouin/Erbium-Ytterbium co-doped fiber ring laser, which uses a length of 80-cm Erbium-Ytterbium co-doped fiber as both the Brillouin gain and linear gain media. The 976-nm pump threshold is only 80 mW when the Brillouin pump power is 20 mW. The output power of this laser … WebSep 23, 2024 · Thus, variations in Brillouin linewidth can, in turn, yield insights on liquid-to-solid phase transitions occurring in intracellular compartments, such as stress granules, in response to protein ...
WebMay 3, 2024 · This “pixelation” noise becomes dominant at channel sizes that approach and exceed the spectrometer PSF. In SBS, being the spectral resolution limited only by the laser linewidth, which is much smaller than the typical Brillouin linewidth, the spectral PSF is given by the natural broadening Γ B, which is sample-dependent .
