Results are presented for color center, and semiconductor, laser pumping of the 1.82 {mu}m transition in a thulium-doped fluoride fiber. As an amplifier small signal gain efficiencies of 8.1 dB/mW were attained with a maximum gain of 36.5 dB being for around 17-18 mW of launched pump power. As a laser a maximum slope efficiency of 84% and a minimum threshold for oscillation of 340 {mu}W was also demonstrated for this system. Furthermore by suppressing all reflections down to <36 dB superfluorescent or ASE output was observed. In achieving efficient operation with a diode laser pump source this system shows strong commercial potential.
