The University of California at Santa Barbara (UCSB) free electron laser (FEL) program was initiated in January of 1980 at the Quantum Institute to study the operation of electrostatic accelerator free electron lasers. A detailed discussion of the operation of these devices can be found elsewhere in this book under the title 'Electrostatic Accelerator Free Electron Lasers'. The main goal in this paper is threefold: (1) to present a summary of the UCSB experimental FEL program to date, (2) to discuss future FEL device development objectives, and (3) to talk briefly about the future of applied research at UCSB. There is presently in existence a large number of high energy electron accelerator machines that can be readily used as sources of electron beams suitable to demonstrate the basic operation of free electron lasers. This is the case, for example, with the super-conducting electron accelerator at Stanford University where the first operation of the free electron laser was demonstrated in 1975, and where the potential operating characteristics of FEL's such as high power, high efficiency and broadband continuous tunability were clearly delineated. To realize all of the above predicted operating capabilities of free electron lasers it is, however, necessary to develop suitable electron beam sources.

There is presently in existence a large number of high energy electron accelerator machines that can be readily used as sources of electron beams suitable to demonstrate the basic operation of free electron lasers. Electrostatic accelerators appear to offer great promise for generating the electron beams needed by free electron lasers. Their conventional technology is well understood and there are good reasons to believe that this technology can be used with free electron lasers. The major components of the system are: Accelerator high pressure tank; HV generator; Electron gun; Electron accelerator column; FEL periodic magnet and optical resonator; Electron decelerator column; Electron collector, and Ancillary electron beam optics and control system.

The volume contains the proceedings of the 7th Course on Physics and Technology of Free Electron Lasers of the International School of Quantum Electronics, which was held in Erice (Italy) from 17 to 29 August 1980, under the auspices of the "Ettore Majorana" Centre for Scientific Culture. The level of this Course was much closer to a workshop than to a school, and "Advances in Free Electron Lasers" might have been an appropriate title. Many of the world's leading scientists in the field (among them, the inventor of FEL, J. M. J. Madey) were brought together to review the accomplishments of FEL experiments, as well various trends in FEL theory. In editing this material we did not modify the original manu scripts except to assist in uniformity of style. The papers. are presented without reference to the chronology of the Course but in the following topical arrangement: A. "Fundamentals of free electron lasers," a group of tutorial papers; B. "Free electron lasers operating in the Compton regime," where theories and experiments of FELs based on Compton scattering are reviewed; C. "Free electron lasers operating in the Raman regime," a dis cussion of FELs based on Raman scattering; D. "Optical klystrons," where the possibility of this class of FEL is discussed from a theoretical viewpoint; E.

The UCSB FEL experimental program was initiated January 15, 1980 at the Quantum Institute of the University of California at Santa Barbara. It's principal objective is to demonstrate the operation of electrostatic-accelerator free-electron lasers in (1) the FIR-submillimeter region at high average power and high overall efficiency using a single stage FEL; and (2) the visible-IR region with modest power and modest overall efficiency using a two-stage FEL. An important feature of the UCSB FEL is the recovery of the spent electron beam. Both (1) the average laser power and (2) the overall efficiency of the FEL increase with increased electron beam collection efficiency. Optimum laser performance can be achieved with this device provided only a small fraction of the total electric charge stored in the beam is lost while transporting it through the system. Realization of this low charge loss condition can be achieved only if a very high quality electron beam can be produced and maintained throughout the electron accelerator and transport system.

The University of California, Santa Barbara (UCSB) Free Electron Laser (FEL) project was initiated in 1981 to test the idea of using an electrostatic accelerator in a recirculating beam mode to produce high-power, continuously tunable, coherent far infrared radiation. The development and application of this device to condensed matter research are briefly recounted. Emphasis was on semiconductor research and two-photon experiments. (RWR).

This book is a reference text for all those working in free-electron laser research as well as being a learning aid for physicists and graduate students who wish an introduction to this field. Only a basic understanding of relativistic mechanics and electromagnetism is presupposed. After an overview of early developments and general principles of operation, the different models that can be used to describe free-electron lasers are presented, organized according to their range of applicability. The relevent conceptual and mathematical constructs are built up from first principles with attention to obtaining the practically important results in a simple but rigorous way. Interaction of the undulator with the driving electron accelerator and the laser cavity and design of undulator magnets are treated and an overview is given of some typical experiments.
