In this contribution, we focus on development of a thulium-doped fiber-optic amplifier working in spectral range from 1800 to 2050 nm. The amplifier is core-pumped using an erbium-doped fiber laser emitting at 1565 nm with maximum output power of ~2 W. We use in-house developed and manufactured silica-based thulium-doped fibers and commercially available optical components in the setup. A tunable thulium-doped fiber laser was used as signal source allowing us to cover the whole spectral range of interest. The basic parameters of the amplifier with respect to used configuration, fiber lengths, and spectral wavelength are presented and discussed
