Efficient emission at 1.38 mu m wavelength from holmium (Ho3+)-doped low-phonon-energy gallate bismuth lead (GBL) oxide glasses, owing to the Ho3+: (S-5(2), F-5(4)) -> I-5(5) transition, was observed, and the stimulated emission cross section was calculated to be 2.4 x 10(-21) cm(2). Population inversions between the (S-5(2), F-5(4)) and 5I5 levels have been achieved, and a broad gain bandwidth from 1350 to 1450 nm was obtained. The large product of emission cross section and measured lifetime also support this characteristic. The results indicate that a Ho3+-doped GBL glass system is a promising candidate for the development of E-band (1360-1460 nm) fiber-optic amplifiers. (C) 2010 Optical Society of America
