Bi-doped fiber lasers and amplifiers for a spectral region of 1300-1470 nm

Opt Lett. 2008 Oct 1;33(19):2227-9. doi: 10.1364/ol.33.002227.

Abstract

Bismuth-doped fiber lasers operating in the range 1300-1470 nm have been demonstrated for the first time, to our knowledge. It has been shown that Bi-doped alumina-free phosphogermanosilicate fibers reveal optical gain in a wavelength range of 1240-1485 nm with pumping at 1205, 1230, or 808 nm.
