摘　　要：采用渐变摇摆场技术进行了拉曼型自由电子激光实验,获得了最大辐射功率31MW、波长8～10.4mm的微波辐射输出,电子能量转换效率达9.68％。实验表明,对强流低能(0.45MeV)电子束拉曼自由电子激光器,渐变摇摆场比恒定摇摆场的自由电子激光器能量转换效率高2.6倍。Experiments on a Raman FEL with a tapered field have been done. A maximum radiution output of 31MW at 8 ~ 10.4mm has been obtained with an energy efficiency of 9.68%. The tapering technique is effective in increasing the efficiency in the Raman FEL for large current and low energy electron beam.
