Experiments at Stanford approach a free‐electron laser

Great expectations for a powerful, high‐resolution laser, completely tunable from the infrared through the vacuum ultraviolet region, have been raised by some recent work at Stanford University. Experiments there show that a “free‐electron laser”—one in which free electrons stimulate the emission of magnetic bremsstrahlung in a spatially periodic transverse magnetic field—could be a practical device.
