Web1 Introduction. Free electron laser (FEL) is a coherent light source with broad-band wavelength tunability. FEL is the only tunable laser in the far-infrared (FIR) region. FIR … A free-electron laser (FEL) is a (fourth generation) light source producing extremely brilliant and short pulses of radiation. An FEL functions and behaves in many ways like a laser, but instead of using stimulated emission from atomic or molecular excitations, it employs relativistic electrons as a gain medium. Radiation is … See more To create an FEL, a beam of electrons is accelerated to almost the speed of light. The beam passes through a periodic arrangement of magnets with alternating poles across the beam path, which creates a side to side See more Free-electron lasers require the use of an electron accelerator with its associated shielding, as accelerated electrons can be a radiation hazard if … See more The FEL prize is given to a person who has contributed significantly to the advancement of the field of Free-Electron Lasers.
