A. Mathur et al., Over 1W fibre-coupled power from single semiconductor source for pumping of Raman fibre amplifiers and erbium-doped fibre amplifiers, ELECTR LETT, 36(5), 2000, pp. 410-411
For the first time, over 1W of optical power has been coupled into singlemo
de fibre from a single semiconductor laser diode operating at 1.45 mu m. Th
is device meets the need for a compact high power source for pumping of erb
ium-doped Fibre amplifiers and for Raman amplification in fibres.
