In this paper we show the analysis of Thulium Doped Fibre Amplifier(TDFA) gain dependence on pump laser wavelength and thulium doped fibre length. Thulium doped fibres of lengths varying from 0.5m to 3m are pumped with 785nm and 1550nm lasers in single and dual pumping schemes. Small signal gain up to 16dB was achieved at 2μm for a low pump power of 150mW. A potential wide amplifications bandwidth ranging from 1680nm to 2025nm is observed in the Amplified Spontaneous Emission(ASE) spectrum.
