A diode-pumped, thulium-doped, fluorozirconate fibre amplifier has been used to amplify high-power pulses from a modulated AIGaAs diode laser at 805nm, using a 100mW single-stripe diode laser at 785nm as the pump source. Internal gains in excess of 1 8dB were observed in the small-signal regime. The greatest peak output power, observed for a launched pump power of 47mW, was 12.5W for pulses of 15ps duration driven at a repetition rate of 7 MHz.
