The amplitude and width of the ultrashort pulses depend on the performance of the generator’s electronic elements. The usage of step recovery diodes (SRDs) with picosecond switching time can lead to a significant increase in device cost. In this letter, nonlinear transmission line (NLTL) was built and tested using commercial-off-the-shelf components to improve the performance of the generator that is based on inexpensive diodes. The method to control output pulse duration by keeping the constant amplitude was proposed. Measurement results show that generated ultrashort pulse can be compressed using NLTLs and the output amplitude of the compressed pulse is 54 V and the duration is 240 ps.

非线性传输线在皮秒脉冲锐化中的应用


超短脉冲的幅度和宽度取决于发生器电子元件的性能。使用具有皮秒开关时间的阶跃恢复二极管 (SRD) 会导致器件成本显着增加。在这封信中，使用商用现成组件构建并测试了非线性传输线 (NLTL)，以提高基于廉价二极管的发电机的性能。提出了通过保持幅值恒定来控制输出脉冲持续时间的方法。测量结果表明，可以利用NLTL对产生的超短脉冲进行压缩，压缩脉冲的输出幅度为54 V，持续时间为240 ps。
