S. Magne et al., AN YTTERBIUM-DOPED MONOMODE FIBER LASER - AMPLIFIED SPONTANEOUS EMISSION, MODELING OF THE GAIN AND TUNABILITY IN AN EXTERNAL-CAVITY, Journal of luminescence, 60-1, 1994, pp. 647-650
The spectral behavior of the amplified spontaneous emission of an ytte
rbium-doped monomode fiber is described and the site-selective excitat
ion tunability is explained. Then, the fiber gain is modeled, taking i
nto account the fiber length and the pumping wavelength to optimize a
three-level scheme room-temperature laser operation at 976 nm.
