摘要

The feasibility of direct laser diode pumping of Bi-doped fiber lasers at the wavelengths of 915 and 975 nmnwas examined by measuring excited state absorption in Bi-doped silicate fibers for the wavelength range ofn900–1250 nm. When the Bi-doped fibers were pumped at 1047 nm a strong excited state absorption wasnfound at 915 and 975 nm, whereas no significant excited state absorption was observed in the 1080 nmnpumping band nor in the emission band, u00011160 nm, of Bi-doped fiber lasers. © 2009 Optical Society ofnAmerica
