摘　　要：提出微波系统宏脉冲内相位任意变化的方法 ,改善自由电子激光功率输出 .以自由电子激光功率输出为指示 ,用计算机控制任意函数发生器改变宏脉冲内微波相位 ,短的建立时间和大的饱和功率会同时获得 .北京红外自由电子激光器进行的实验证明这种方法可以有效地提高自由电子激光的功率输出 .A new method of arbitrary variation of the phase of RF system during the macropulse to optimize the FEL output is proposed. In this method, the FEL output is used as a tuning indicator to adjust the RF phase in different time intervals of the macro pulse with computer controlled arbitrary function generator. In this case, shortest build up time and largest saturated power in a macro pulse can be simultaneously achieved. Experimental testing of this method has been carried out in Beijing IR FEL oscillator and proves to be effective in increasing the power output of BFEL facility.
