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, approximately 1160 nm, of Bi-doped fiber lasers.
通过测量铋掺杂硅酸盐光纤在900 - 1250 nm波长范围内的激发态吸收，研究了在915和975 nm波长下直接用激光二极管泵浦铋掺杂光纤激光器的可行性。当铋掺杂光纤在1047 nm波长下泵浦时，在915和975 nm波长处发现了强烈的激发态吸收，而在1080 nm泵浦波段以及铋掺杂光纤激光器约1160 nm的发射波段均未观察到明显的激发态吸收。
