TERS is another method for generating enhancement of the Raman signal. Like nanoparticle-based SERS, this method is also based on probing the inherent nanoscale environment of the sample in close ...

Unlike erbium-doped fiber amplifiers (EDFAs), which boost wavelengths in the 1530-1610 nm range, a Raman amplifier can increase the signal strength of any wavelength by pumping at 13THz more than ...
