Gas Optics Applicable to Free Electron Laser Technology

Abstract

The free electron laser has the potential of being a highly efficient short wavelength laser. The designs of these lasers are hampered by excessively long optical cavities required by practical considerations of the mirror reflectors. A solution to this problem may be the use of defocussing gas optics in conjunction with the traditional mirror optics. Estimates show that the length of the optical cavity may be reduced by over an order of magnitude with this approach. A program of experimental and theoretical research was carried out to study the various aspects of gas optics for use with the free electron laser. Keywords: Gas optics; Free electron lasers; Aerodynamic windows. (jhd)
