Abstract
The operation of a new ultra compact diffraction grating coupled free-elect
ron laser (FEL) has been demonstrated. The basic elements of the device whi
ch is termed a grating coupled oscillator (GCO) are the beam in a scanning
electron microscope (SEM) and a diffraction grating which is mounted in the
e-beam focal region of the SEM. The e-beam is controlled by the SEM's elec
tron optical system and distributed feed back is provided by the grating it
self. Recent experimental results are presented and techniques for extendin
g the wavelength and power coverage are discussed. (C) 1999 Elsevier Scienc
