The Los Alamos Free-Electron Laser
Abstract
During the past year the Los Alamos free-electron laser (FEL) oscillator has demonstrated high peak and average power (10 MW and 6 kW), broad-wavelength tunability (9-35 microns), and near-ideal optical quality (0.9 Strehl ratio). An electron energy-extraction efficiency of 1 percent was measured. The predicted production of synchrotron sidebands also was observed in the broadened optical spectrum. As shorter wavelengths and higher powers are pursued, higher currents with improved beam quality will be required. Advanced injectors and energy-recovery systems are being developed to meet these demands.
