查询词典 Pulse

The experiment was performed at the Asterix IV iodine laser with a prepulse 5 ns before the main pulse. Under optimum focusing conditions for main pulse and prepulse the X-ray laser beam splits into two beamlets along the target surface at its output end of the 2.5 cm long plasma column. The splitting was still observed when the prepulse alone was defocused.

实验发现在抽运激光主、预脉冲最佳聚焦条件下， X射线激光束在2.5 cm长的线状等离子体输出端沿靶面方向分裂成两束；在抽运预脉冲单独散焦条件下，仍然观察到这一分裂现象；但是当抽运主、预脉冲同时散焦时，这一分裂现象逐渐消失并获得了半宽度只有40 μm的非常窄的近场像。

In order to testify a pulse contrast measurement's dynamic range in a simple and clear way, this article uses a series of pulses with equal intervals and equal ratios of intensity as a criterion, which reflected from back surface of a 0°reflector, and first discuss the calibration of pulse contras measurement and verify it by experiments in the world.

The gating of PMT was realized with the method of adding the applied gating and gain-control nano-second pulse, and by changing the electric potential difference between the cathode and the first dynode. The gain control of PMT was complemented by the aid of adding the high voltage pulse to the last dynode of PMT to change the electric potential difference between the last dynode and front dynode.

采用给PMT外加选通和变增益纳秒电脉冲的方法，通过改变PMT光阴极与第一打拿极之间电势差，实现PMT选通；借助给PMT最后一个打拿极外加变增益高压脉冲改变PMT最后一个打拿极与前置打拿极间的电势差，实现PMT变增益。
