With the publication of the first experimental measurements performed at the facility, the European X-ray Free-Electron Laser (EuXFEL) has passed another critical milestone since its launch in September 2017. It is the first ...
If you want to get the greatest benefit from a beam of light—whether to detect a distant planet or remedy an aberration in the human eye—you need to be able to measure its beam front information.
Although critical for varied applications, such as cutting and welding, surgery and transmitting bits through optical fiber, lasers have some limitations – namely, they only produce light in limited wavelength ranges. Now, ...
An international research group, together with scientists from the MSU, have developed a time-resolved spectroscopy method that allows studying fast processes in samples. The new method works by analyzing quantized light ...
MXenes, conductive materials widely used in many industries, now have one more promising application: helping lasers fire extremely short femtosecond pulses, which last just millionths of a billionth of a second. The finding, ...
In a significant breakthrough, scientists at the Tata Institute of Fundamental Research (TIFR), Mumbai, have devised a high-power radiation source in the terahertz (THz) region of the electromagnetic spectrum. This study, ...
(Phys.org)—It has taken more than 20 years, but researchers have demonstrated for the first time that femtosecond lasers can be used to structurally manipulate bulk silicon for high-precision applications. Since the late ...
Researchers from ITMO University have built a setup for recording holograms of tiny objects like living cells at femtosecond speeds. The new method reconstructs the phase topography of a sample according to deformations that ...
Tiny micro- and nanoscale structures within a material's surface are invisible to the naked eye, but play a big role in determining a material's physical, chemical, and biomedical properties.
Extremely short, configurable "femtosecond" pulses of light demonstrated by an international team could lead to future computers that run up to 100,000 times faster than today's electronics.
