利用粒子经典理论建立了自放大自发辐射(SASE)自由电子激光高增益自洽方程组，编写了稳态Matlab-SASE-FEL数值计算程序；对LCLS装置参数进行了优化，给出了辐射光的各特征参数。该程序的主要优势在于基于Matlab的便利性可方便地进行后处理数据，对X射线FEL理论研究的深化和实验装置的设计和改进具有重要的意义。

Free-electron laser (FEL) wavelength can continuously tuning (up to X-ray band) with high power and high efficiency. FEL has a great potential in femtosecond science, biological molecules, nano science research field and etc. In this paper, we established the self-consistent equations of self amplified spontaneous emission (SASE) FEL by using the classical particle theory and developed the steady-state Matlab-SASE-FEL numerical code. The LCLS facility parameters were optimized and the characteristic of the radiation laser light was presented. The main advantage of this code is that the data can be easily post-processed based on the convenience of Matlab tool.
