利用雪崩管堆驱动LiNbO_3电光偏转器对激光脉冲进行快速偏转,实现幅度稳定的纳秒整形激光脉冲;激光脉冲振幅不稳定度从振荡器输出的单纵模调Q激光脉冲的10％(RMS)降低到4％(RMS),大大改进了纳秒量级整形激光脉冲幅度稳定性。
The laser pulses are quickly deflected by the avalanche tube stack driven LiNbO_3 electro-optic deflector to achieve a stable amplitude nanosecond laser pulse. The amplitude of the laser pulse instability rises from 10% (RMS) of the single longitudinal mode Q laser pulse output by the oscillator, Down to 4% (RMS), greatly improving the nanosecond magnitude laser pulse amplitude stability.
