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.

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.

Book excerpt: The Los Alamos free-electron laser (FEL) amplifier experiment was designed to demonstrate high efficiency for transfer of energy from an electron beam to a light beam in the magnetic field of a tapered wiggler. Initial results indicate an energy transfer consistent with theory. Distinct groups of decelerated electrons as well as accelerated electrons are clearly present in the energy spectrum of electrons emerging from the wiggler when the laser light is present. The observed energy decrease for the electrons captured in the decelerating bucket is approx. 6% and the average decrease of the entire energy distribution is approx. 2% for the conditions of these initial measurements.

Book excerpt: Experiments with a tapered-wiggler free-electron laser have demonstrated extraction of about 3% of the energy from the electron beam and measured the corresponding optical emission. These results are in excellent agreement with theory and represent an order-of-magnitude improvement over all previous results.

Book excerpt: Results obtained with a tapered-wiggler free-electron laser demonstrate the concepts proposed by Morton for enhanced efficiency and show deceleration of electrons by as much as 7%, and extraction of more than 3% of the total electron-beam energy as laser energy when the laser is operated as an amplifier. The experiment is presently being reconfigured to examine its performance as a laser oscillator.

Available in PDF, EPUB and Kindle. Book excerpt: Experiments have been concluded demonstrating energy recovery in conjunction with the Los Alamos free-electron laser. In this paper, we discuss measurements of electron-beam transport during decelerations greater than 70% from 21 MeV down to 5 MeV. Power-flow measurements demonstrate the efficient conversion of beam power back into rf power and its reuse in the accelerator. We also describe instabilities of the system and compare them with simulations.

Available in PDF, EPUB and Kindle. Book excerpt: The applications of ''streak systems'' that provide time-resolved diagnostic data for the Los Alamos free-electron laser energy recovery experiments have been extended in the last year. We have used these systems with time resolutions of 10 .mu.s, approx. 20 ps, and 2 to 8 ps to address both macropulse and micropulse issues. As one example, the time-dependent extraction efficiency behavior during the macropulse is presented. In addition, the effects on the electron micropulse temporal shape of several accelerator parameters have been studied. These results include the evidence of electron beam peak currents that approach 200 A.
