Figures & Tables(6)
Fig. 1. Experimental setup of the TDFL. TDF: Tm-doped fiber; PM: phase modulator; IM: intensity modulator; and FG: function generator.
Fig. 2. (a) Oscilloscope traces of pulse bursts train, (b) single pulse burst, and (c) individual pulses in one burst.
Fig. 3. (a) Dense pulse train when only intensity modulation is on and (b) zoomed-in pulse train.
Fig. 5. Oscilloscope traces of individual pulse shape control via intensity modulation. (a) Pulse shape with a sharp top and a subsequent flat top. (b) Pulse shape with round top. (c) Pulse shape with step-flat top. (d) Mode-locked pulse shape.
