The feasibility of direct laser diode pumping of Bi-doped fiber lasers at the wavelengths of 915 and 975 nm was examined by measuring excited state absorption in Bi-doped silicate fibers for the wavelength range of 900 1250 nm . When the Bi-doped fibers were pumped at 1047 nm a strong excited state absorption was found at 915 and 975 nm , whereas no significant excited state absorption was observed in the 1080 nm pumping band nor in the emission band, 1160 nm , of Bi-doped fiber lasers.
