Results are presented for color center, and semiconductor, laser pumping of the 1.82 /spl mu/m transition in a thulium-doped fluoride fiber. As an amplifier small signal gain efficiencies of 8.1 dB/mN were attained with a maximum gain of 36.5 dB being achieved 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 330 /spl 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.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
