摘要

发展民用和军用激光应用所面临的主要问题在于，如何获得接近连接某些材料原子的键长度的短脉冲。本文编制了一个可执行程序来模拟和分析超短自由电子激光脉冲的产生;它包含几个参数，指导在飞秒(fs)的时间内创建短脉冲。通过对仿真结果的分析，可以得出结论，使用具有明显短波长(11.4 ~ 190.2)的存储环自由电子激光器法布里-珀罗谐振器输出激光束，可以产生持续时间约为7.4 ~ 87.4 fs的超短脉冲。KEYWORDSHomogenous扩大;SR-FEL;波纹机;能量扩散增益;Q -开关

Ultra-Short Pulses Generation of Free Electron Laser

The major problem facing the development of civil and military laser applications lies in the attempts to obtain short pulses close to the length of the bond that connects the atoms of certain materials. In this paper, an executable program has been constructed to simulate and analyze the generation of ultra-short free electron laser pulses; it contains several parameters directing the creation of short pulses within a time duration of femtoseconds (fs). On analyzing the simulation results, it can be concluded that it is possible to generate ultra-short pulses with a duration of about 7.4 – 87.4 fs with the storage ring free-electron laser Fabry–Perot resonator with noticeably short wavelengths (11.4–190.2) for the output laser beam.
