Few-cycle pulses at wavelengths longer than 10 µm are important for fundamental studies of the non-equilibrium properties of condensed matter, i.e., solids and liquids, and exhibit a high application ...

WASHINGTON--(BUSINESS WIRE)--Terahertz (THz) radiation, a slice of the electromagnetic spectrum that occupies the middle ground between microwaves and infrared light, is rapidly finding important uses ...

To capture fast-moving action in a dimly lit environment, a photographer will use the combination of a fast shutter speed and a quick burst of light. Laser physicists employ the same principle – ...

High intensity: Claudia Gollner and colleagues have boosted the energy delivered by terahertz pulses. (Courtesy: TU Wien) Intense, ultrashort pulses of terahertz radiation have been generated with an ...

Intense ultra-short pulses have sophisticated generation processes, complex metrology schemes and their applications are ubiquitous, spanning atomic-molecular physics, chemistry, material science, ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. The 2018 Nobel Prize in Physics was announced this morning "for ...

A time-dependent electric current emits an electromagnetic wave, a basic physical effect exploited in telecom antennas. Transferring this mechanism to the ultrashort length and time scales of the ...

For a long time, scientists have been looking for simple methods to produce infrared laser pulses. Now a new method has been presented that does not require large experimental setups; it can be easily ...

A new light source generates ultrashort infrared pulses at wavelengths around 12 µm with previously unattained peak intensity and stability. First experiments in vibrational spectroscopy on water ...
