Abstract

An actively mode-locked and passively Q-switched thulium doped fluorozirconate fibre laser using an AlGaAs/GaAs multi-quantum-well (MQW) asymmetric Fabry-Perot modulator (AFPM) is reported. This is the first demonstration of active mode-locking of fibre lasers using MQW modulators. Mode locked pulse trains of 6ns pulsewidth are obtained within a Q-switched envelope of 400ns duration.
