Paper Abstract

The laser pulse shape should be varied to meet different requirements of the inertial confinement experiments. Chirped pulse-stacking is an effective method to obtain a long pulse with desired pulse shape using short pulses. We introduce a method to obtain a long pulse shaped by chirped pulse stacking in fiber time-delay lines. We demonstrate an all fiber pulse shape generator that can generate arbitrary pulse shapes by stacking a set of 20-ps pulses output from fiber mode-locking laser. The device offers a 2.2ns arbitrary waveform optical pulse with power up to 30dBm, bandwidth of 0.2nm and a rise time less than 50ps. The output optical pulse has a temporal adjustment precision of 32bit and an amplitude adjustment precision of 10bit. Experimental and theoretical results show that the generator provided the required stability, flexibility, fast rise time and high contrast pulse for laser fusion research.
