1 INTRODUCTION

Although the same physical principles govern the operation of free electron lasers (FELs) in all wavelength regions, the costs and benefits of FELs depend strongly on wavelength. Therefore, this report is organized largely according to spectral region. Chapter 2 describes the history of free electron lasers, the principles of their operation, and their properties, and it lists existing and some of the proposed FELs.

Chapter 3, Chapter 4, Chapter 5 through Chapter 6 each deal with a specific spectral region: Chapter 3 covers the far infrared from 1000 to 10 µm; Chapter 4, the region from 10 µm to 200 nm, including the near infrared, the visible, and the ultraviolet; Chapter 5, the region from 200 to 10 nm, a region referred to as the vacuum ultraviolet and extended ultraviolet; and Chapter 6, the x-ray from 100 to 1 Å. Each chapter describes the present capabilities of photon sources, including FELs and other advanced coherent light sources if they exist, as well as more conventional sources; in addition, each outlines some proposed FELs that have been envisioned but do not currently exist. Also presented in each chapter is a discussion of scientific opportunities that will require sophisticated sources of photons, along with comments on which source or combination of sources is likely to be most appropriate. In discussing scientific opportunities, the committee has not tried to be exhaustive in listing all possible experiments that might use FELs or other advanced coherent light sources. Instead, it has selected, from among the many potential opportunities of which it was informed, those that seemed to represent the most interesting problems and the most exciting possibilities. Finally, each chapter ends with a list of the committee's findings and recommendations.

There were some general concerns that apply to the future development of free electron lasers in all wavelength regions that the committee believed were important but that did not fit into the chapters on individual wavelength regions. These are discussed in Chapter 7.

As a basis of comparison among various photon sources, Figure 1, Figure 2, Figure 3, Figure 4, Figure 5 to Figure 6 give the peak power, pulse energy, and average power of various photon sources as a function of wavelength. Because photon sources have many important properties other than the three described in these figures, the figures cannot be used by themselves to identify the source of choice for any given experiment. They may, however, be qualitatively useful to readers of this report.
