2001年5月在日本大学实现了自由电子激光器（FEL）的首次激射。在脉冲宽度和自由电子激光的长工作时间内，电子束的能量稳定性出现了问题。通过函数发生器和反馈电路补偿射频相位漂移，提高了能量稳定性。
The first lasing of the free electron laser (FEL) was achieved in May 2001 at Nihon University. Problems occurred regarding the energy stability of the electron beam in the pulse duration and the long operation time for the FEL. The energy stability has been improved by compensation of the RF phase drift with a function generator and a feedback circuit.
