Abstract: PROBLEM TO BE SOLVED: To provide an ASE light source that can obtain high outputs over a wide wavelength range in the vicinity of 1,470 nm. SOLUTION: This ASE light source uses a Tm-doped optical fiber 1 and two kinds of excitation light rays of first excitation light corresponding to the energy of Tm ions between<3> H6 and<3> F4 levels and second excitation light corresponding to the energy of Tm ions between<3> F4 and<3> H4 levels.
