Q-switched neodymium-doped phosphate glass fibre lasers.
IEEE Journal of Quantum Electronics, 29, (7), . (doi:10.1109/3.237492).
The operation of a short-pulse, Q-switched, neodymium-doped fiber laser operating at 1.054µm is described experimentally and theoretically. The laser is efficiently pumped with a single-stripe AlGaAs laser diode and emits >1kW pulses. It is seen that due to high gain, short pulses with high energy extraction efficiency can be obtained. The feature of broad emission lines associated with rare-earth-doped glasses is exploited to demonstrate tunable, Q-switched operation over a 40 nm tuning range.
