摘　　要：We present a compact Tm-doped fiber laser(TDFL)to generate pulse bursts at 1.92μm based on phase and intensity modulations.A phase modulator(PM)and an intensity modulator(IM)were included in the linear TDFL cavity to perform the simultaneous active intracavity phase and intensity modulation.Stable pulse bursts have been achieved with tunable repetition rate in the range of 36–44 kHz(modulated by the PM)and duration of about 9.6μs.The repetition rate of the individual pulse in a burst is about 9 MHz(modulated by the IM),and the pulse width is about 6 ns.By changing the IM signal’s repetition rate and duty cycle,different individual pulse shapes are obtained with pulse durations between 6 and 34 ns.
