The plasma-loaded Raman FEL is widely and thoroughly studied in thispaper. The main content includes: thermal plasma-loaded FEL, plasma-loadedFEL with an axial guide magnetic field, and two-stream FEL with anAGMF.In this paper, the basic principle of FEL is introduced and the lineartheory is described in brief firstly.

本文对等离子体填充喇曼型的自由电子激光作了广泛深入的研究，主要内容包括：研究了热等离子体填充的FEL；分析了具有引导磁场的等离子体填充的FEL；进一步探讨了具有引导磁场的双电子注FEL。

The third, since the electrons in the plasma are accelerated and ions move together, some harmful effects are also observed, such as both output powers of RBWO and FEL decrease versus the increase of plasma density. The results agree with the results of linear fluid model. In the unmagnetized plasma-loaded RBWO-FEL, output powers of pump source and FEL are obtained only in a narrow plasma density range and both have maximum. The results of simulation are in good agreement with the experimental results.

模拟分析了磁化等离子体填充的RBWO-FEL，尽管没有发现等离子体填充后RBWO及FEL输出功率的成倍增长，但是观察到等离子体的引入对RBWO-FEL产生以下影响：泵波及FEL的辐射频率的线宽得到明显增加；在较高的等离子体密度下，TM〓模将会被完全抑制；首次观察到T-G模振荡及功率输出，结果同线性理论计算结果基本一致；等离子体中的电子被加速及背景离子的移动将对器件工作产生不利影响。

The dissertation is concentrating on the topic of a high power, tunable, millimeter wave free electron laser. The tunable ability of the mm wave FEL is studied. FEL powers are improved by novel variable parameter wigglers. A high brightness electron beam is achieved for FEL. These technologies are very important for realization of high power compact free electron lasers.
