Abstract

A diode-pumped Tm-doped double-clad fiber-optic amplifier is reported that provides up to 5kW of peak power at pulse durations of 30ns and a repetition rate of 33.5kHz. When the repetition rate is increased to 123.6kHz, the peak power drops to 1.5kW, while the average output power of the amplifier stays at 6.5W with a slope efficiency of 34.9%. As an amplifier the fiber can be saturated by a very low average launched input power of only 36mW at 1.87μm and yields the same average output power as in a fiber laser or amplified spontaneous emission source setup for all the repetition rates investigated. The peak powers reported are to the author’s knowledge the highest generated by Tm-doped fiber lasers or amplifiers at repetition rates above 1kHz with simultaneously short pulse durations of 30ns.
