Specially, the thermal lens effect is intensified due to the long tail attached to pulse, which leads to decreasing of conversion efficiency if pulse repetition rate is enhanced.

特别由于脉冲附带长的拖尾加剧了热透镜效应，使得脉冲重复频率的增加引起转换效率的降低。

Then, transform it through the pulse sharpening circuit consisting mainly of capacitances and magnetic switches, finally outputting the high voltage and high repetition rate nanosecond pulses.

然后运用脉冲功率技术，通过由电容器和磁开关等组成的脉冲陡化电路对正弦电压波形进行改形，最后输出纳秒级上升前沿、高重复频率的高压脉冲。

In the atmosphere, on propagation of High-Intensity lasers of high pulse repetition rate and narrow pulsewidth, the SRS will be serious because of molecular memory effects.

对于高重复率和脉宽较窄的强激光在大气传输中，由于分子的储存效应，受激喇曼散射较严重。
