In high-power solid-state laser, initiative pulse shaping can help improve the output laser’s performance. The evaluation
for output laser pulse is also incomplete. In this paper, we propose a method of initiative pulse shaping by using arbitrary
waveform generator (AWG), and establish a relatively complete evaluation system for the output pulses shape
simultaneously. It achieves the super-Gaussian pulse output with high SNR (signal-to-noise ratio). As a consequence, a
square laser pulse with pulse adjustable width ~5ns, rising time 197ps is obtained. The power imbalance of the output
square pulse is 3.72%. The similarity between the eight-order super-Gaussian pulse and the one we get from experiment
reached 99%.
