英文摘要：

We studied the dynamic response characteristics of the PZT driver response for the irregular signals. When the frequency of the input sinusoid signal is in the range of 0-10 kHz, the distortion of the output signal is less than 3.19%. The rise-time and the fall-time were only 4.6 μs and 18.4 μs respectively when rectangular signal was inputted. The results show that the PZT driver has wonderful dynamic response characteristics for irregular signals, and the frequency range is wide and the response speed is very fast, so it is suitable to be applied to the ultrafast actively mode locked fiber laser system.
