Tm<sup>3+</sup>-doped tellurite glass is investigated as a host for a broadband amplifier at 1.47 μm. The Tm<sup>3+</sup> fluorescence spectrum, lifetime, and cross section in tellurite glass are compared with those in fluorozirconate glasses. The advantages of a Tm<sup>3+</sup>–tellurite amplifier, especially when it is employed in combination with an Er<sup>3+</sup>–tellurite 1.55-μm amplifier, are discussed.
