21Free-Electron Laser Safety Challenges
Focus on the Jefferson Lab Free-Electron Laser
Introduction
The free-electron laser (FEL) technology dates back to the 1970s. When compared with conventional lasers, the significant difference lies with the laser medium. In the FEL, the laser medium is no longer a chemical, such as a gas or a crystalline structure, but an electron beam in an oscillatory magnetic field. Current FELs cover a wavelength range from millimeters to angstroms. The advantages of the FEL over conventional lasers include wavelength tunability and high powers that can be obtained in areas of the infrared and ultraviolet spectrum that have not been achieved using conventional lasers.
