Book excerpt: In this paper we review the most recent experimental results of the Los Alamos free-electron laser program. Three major effects will be described: lasing at improved efficiency over that previously attained, electron beam improvement, and energy recovery. An extraction efficiency of 2% was achieved with a wiggler having a 12% wavelength taper. The beam has been improved so that limits to its quality are now caused, not by injector performance, but by wake fields related to the high peak currents achieved. Limits to optical power are set by mirror damage. Experiments are described that demonstrate the successful operation of an energy recovery system. 17 refs., 10 figs., 3 tabs.

Book excerpt: Since the initial oscillator experiments were completed last year, the Los Alamos FEL has undergone some major modifications and additions in preparation for the next set of experiments. The laser performance is projected to be substantially enhanced, the rf energy-recovery technique will be demonstrated, and FEL physics measurements will be expanded. The accelerator is now being tuned with very promising performance. The above experiments will be completed during the next year.

Book excerpt: At Los Alamos, we are building a free-electron laser (FEL) for industrial, medical, and research applications. This FEL, which will incorporate many of the new technologies developed over the last decade, will be compact in size, robust, and user-friendly. Electrons produced by a photocathode will be accelerated to 20 MeV by a high-brightness accelerator and transported using permanent-magnet quadrupoles and dipoles. They will form an electron beam with an excellent instantaneous beam quality of 10 [pi] mm mrad in transverse emittance and 0.3% in energy spread at a peak current up to 300 A. Including operation at higher harmonics, the laser wavelength extends form 3.7 [mu]m to 0.4 [mu]m. In this paper, we will describe the project and the programs to date. 10 refs., 10 figs., 1 tab.

Available in PDF, EPUB and Kindle. Book excerpt: Since the last Lasers '83 Conference, significant progress has been made on the Los Alamos free-electron laser (FEL). Although the previously reported results were in agreement with theory, the data were plagued by gain fluctuations, and no spectral measurements had been obtained. Since then, the source of the fluctuations has been analyzed and substantially reduced. Also, the optical power and spectra dependence on beam emittance, alignment, cavity length, energy spread, and current were systematically studied. This paper reports on the results obtained with a uniform-period wiggler. 3 refs., 14 figs., 2 tabs.

Download or read book A 1-kW Power Demonstration from the Advanced Free Electron Laser written by and published by . This book was released on 1997 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the final report of a one-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The main objective of this project was to engineer and procure an electron beamline compatible with the operation of a 1-kW free-electron laser (FEL). Another major task is the physics design of the electron beam line from the end of the wiggler to the electron beam dump. This task is especially difficult because electron beam is expected to have 20 kW of average power and to simultaneously have a 25% energy spread. The project goals were accomplished. The high-power electron design was completed. All of the hardware necessary for high-power operation was designed and procured.

Book excerpt: Using an electron beam in a magnetic field as the gain medium, free-electron lasers offer a powerful new source of tunable, coherent radiation. Results are just becoming available from several new experiments, but they are confirming the theoretical promise of these devices. Backed up by a strong base of accelerator technology, free-electron lasers are expected to become important in applications requiring wavelengths from the far infrared part of the spectrum to the vacuum ultraviolet.

Book excerpt: The Los Alamos Scientific Laboratory (LASL) has embarked upon an ambitious free electron laser (FEL) research program that will last several years, and includes at least three separate experiments. The overall program is briefly discussed with emphasis on the first gain experiment involving design and construction. The practical features of the experiments and the problem areas found are described. This program uses many kinds of laser systems, but concentrates on the topics of most immediate importance, that is, 10.6-.mu.m wavelength, good beam quality, high power, and short pulses.
