While many research efforts are underway to develop active devices that can function in the challenging terahertz spectrum, others are leapfrogging to try to get some devices operate into the ...

To do attosecond science, you might start with a top-line femtosecond laser that produces millionths-of-billionths-of-a-second infrared pulses. Then, to produce even shorter-wavelength attosecond ...

In the same way that a camera flash can ‘freeze’ rapidly moving objects, making them appear as if they are standing still in photos, extremely short laser pulses can help light up ultrafast processes, ...

Attosecond pulse generation represents a frontier in ultrafast science, allowing researchers to probe electron dynamics on time scales as short as 10⁻¹⁸ seconds. By harnessing the interaction between ...

A team of researchers from the Max Born Institute (MBI), in Berlin, Germany, has for the first time demonstrated attosecond-pump attosecond-probe spectroscopy (APAPS) at a repetition rate of 1 ...

Researchers at Japan's Riken research center have created ultrashort mid-infrared laser pulses using a novel amplification architecture. The work is a further step towards the development and applied ...

A one-quintillionth-of-a-second lasing breakthrough could lead to next-generation X-ray technologies, improving imaging in medical, materials and quantum science. (Nanowerk News) Once only a part of ...
