Paper Abstract

A CWpumped Nd-doped single-mode double-clad fiber laser coiled around a resonant piezo-electric ceramic ring and coupled to an empty external cavity with strong feedback is described. Intensity laser pulses with duration in the 1-2 range are observed as the pump power or the ring drive voltage is increased yielding peak powers up to 25 times greater than average powers. The effect is attributed to strong phase modulation of the fiber laser by the piezo-electric ring which induces FM laser oscillation the external cavity acts as a frequency dependent reflector thus effectively cavity dumping the fiber laser as the oscillation frequency is swept through the narrow transparent windows of the external cavity.
