title: Superfluorescent 1.44 μm bismuth-doped fiber source.
abstract: The first bismuth-doped superfluorescent fiber source (SFS) operating at 1.44 μm was developed. An SFS maximum output power in the double-pass backward configuration reached 82 mW with a fairly high efficiency of 31% at a pump wavelength of 1310 nm. The output spectrum is close to Gaussian shape with FWHM of ~25 nm.
