From page 1...
... Because the free electron laser requires an electron accelerator with its associated shielding, it has not been a device that could be placed in an individual investigator's laboratory and be operated and maintained by graduate students whose primary expertise is in other areas of science. Because free electron lasers are currently used only in central facilities, their utilization in scientific research involves both the cost of the device, and the cost and inconvenience of maintaining a user facility.

From page 2...
... Because of the lack of suitable nonlinear materials, techniques for generating tunable light using commercial laboratory lasers are not effective at wavelengths longer than 10 ~m. It is possible to extend this limit to longer wavelengths with some difficulty using noncommercial instrumentation, but it is unlikely that conventional laboratory lasers will ever be effective at wavelengths longer than 20 ,um.

... There are also existing free electron lasers that operate in this region, but conventional laboratory lasers will probably remain the mainstay of scientific research in this wavelength region. The national expenditure in 1993 on laboratory lasers used in scientific research was approximately $37M.

... Findings I Modern third-generation synchrotrons will cover the vacuum ultraviolet and extended ultraviolet regions well and will provide opportunities to explore much new scientific research in this wavelength region.

... There are existing x-ray sources, both laboratory sources and synchrotrons, but there has never been a high-intensity source of coherent x-rays such as would be produced by an x-ray free electron laser. Therefore, much of the interest in this spectral region arises because many of the possibilities involving coherent x-rays are totally unexplored.

... should continue to be supported. One of the goals of this research and development should be the production of devices of appropriate size and cost to be useful for scientific research on a departmental or individual-investigator scale.
