Abstract

The influence of stimulated Brillouin scattering on laser output performance in 2 µm thulium-doped fiber amplifier was analyzed theoretically. The distribution of optical modes, the effective refractive index, the effective mode field area and the normalized frequency of the double-clad thulium-doped fiber at 793 nm pump wavelength and 1.9~2.1 µm laser waveband were studied.
