A high-power, frequency-tunable electrostatic free-electron maser, being developed at the FOM Institute for Plasma Physics "Rijnhuizen," shows lasing at various frequencies. An output power of 730 kW at 206 GHz is generated by a 7.2-A, 1.77-MeV electron beam, and 380 kW at 165 GHz is generated by a 7.4-A, 1.65-MeV electron beam. In the present experimental setup, without recovery of the spent electron beam power, the pulse length is limited to 12 micros. Nevertheless, the main issues, such as the possibility of high-power, single-mode operation and frequency tuning, have been confirmed. The experimental results and the dynamics of the laser process are well in accordance with simulations.
荷兰等离子体物理研究所“莱因霍伊曾”正在研制的一种高功率、频率可调谐静电自由电子激光器,已实现了在不同频率下的激光发射。由7.2安、1.77兆电子伏的电子束产生了206吉赫兹下730千瓦的输出功率,由7.4安、1.65兆电子伏的电子束产生了165吉赫兹下380千瓦的输出功率。在当前的实验装置中,由于未回收用过的电子束功率,脉冲长度限制在12微秒。然而,诸如高功率单模运行和频率调谐的可能性等主要问题已得到证实。实验结果和激光过程的动力学与模拟结果非常吻合。
