Jefferson Laboratory's kW-level infrared free-electron laser utilizes a superconducting accelerator that recovers about 75% of the electron-beam power. In achieving first lasing, the accelerator operated "straight ahead" to deliver 38-MeV, 1.1-mA cw current for lasing near 5 &mgr;m. The waste beam was sent directly to a dump while producing stable operation at up to 311 W. Utilizing the recirculation loop to send the electron beam back to the linac for energy recovery, the machine has now recovered cw average currents up to 5 mA, and has lased cw with up to 1720 W output at 3.1 &mgr;m.
杰斐逊实验室的千瓦级红外自由电子激光器利用了一台超导加速器，该加速器可回收约75%的电子束功率。在首次实现激光发射时，加速器“直接向前”运行，以提供38兆电子伏特、1.1毫安的连续波电流，用于在5微米附近产生激光。废束被直接送到一个废料堆，同时在高达311瓦的功率下实现稳定运行。利用再循环回路将电子束送回直线加速器进行能量回收，该机器现已回收了高达5毫安的连续波平均电流，并在3.1微米处实现了高达1720瓦输出的连续波激光发射。
