Abstract

A diode pumped, thulium-doped fluorozirconate fibre amplifier has been used to amplify high-power pulses from a modulated AlGaAs diode laser at 80Snm, using a 100mW single stripe diode laser at 785nm as the pump source. Internal gains of up to 19dB were observed for the average launched signal power in the small signal regime, while this was reduced to 16.4dB for average launched signal powers of -8.8dBm. A maximum output power of 12.SW was obtained from 15ps pulses, of incident power 2.1W, being driven at 7MHz so as to avoid saturation; thus showing a system gain of 7.8dB. When operating the amplifier towards saturation, 9.4W amplified output was obtained for 15ps pulses at 36MHz.
