Taking Ultraviolet Light To The extreme
2013-10-04 12:17:25

American Institute of Physics Experiments may help in the design of new sources of extreme ultraviolet light for making integrated circuits with next generation lithography When you heat a tiny droplet of liquid tin with a laser, plasma forms on the surface of the droplet and produces extreme ultraviolet (EUV) light, which has a higher frequency and greater energy than normal ultraviolet. Now, for the first time, researchers have mapped this EUV emission and developed a theoretical...

Electrons Frozen In Flight

Using the world´s fastest laser pulses, which can freeze the ultrafast motion of electrons and atoms, UA physicists have caught the action of molecules breaking apart and electrons getting knocked out of atoms. Their research helps us better understand molecular processes and ultimately be able to control them in many possible applications. In 1878, a now iconic series of photographs instantly solved a long-standing mystery: Does a galloping horse touch the ground at all times? (It...

Scientists Confirm First 'Frequency Comb' To Probe Ultraviolet Wavelengths
2012-02-02 05:00:46

Physicists at JILA have created the first "frequency comb" in the extreme ultraviolet band of the spectrum, high-energy light less than 100 nanometers (nm) in wavelength. Laser-generated frequency combs are the most accurate method available for precisely measuring frequencies, or colors, of light. In reaching the new band of the spectrum, the JILA experiments demonstrated for the first time a very fine mini-comb-like structure within each subunit, or harmonic, of the larger comb, drastically...

New Light Cast On Electrons Heated To Several Billion Degrees
2011-11-21 13:57:00

A new class of high power lasers can effectively accelerate particles like electrons and ions with very intense, short laser pulses.  This has attracted the interest of researchers around the globe, working out the details of the acceleration process which occurs when a laser beam impinges on a thin foil to accelerate ions from the foil´s rear surface to high energies.  The electrons in the foil are heated by the laser pulse, thereby gaining energy.  These electrons in...

Image 1 - A SHARP New Microscope For Next Generation Of Microchips
2011-11-01 04:00:03

Berkeley Lab scientists and colleagues will create an advanced extreme-ultraviolet microscope Moore´s Law, hardly a law but undeniably a persistent trend, says that every year and a half, the number of transistors that fit on a chip roughly doubles. It´s why electronics — from smart phones to flat screens, from MP4 players to movie cameras, from tablets to supercomputers — grow ever more varied, powerful, and compact, but also ever less expensive. Whether the trend...

Word of the Day
  • A small crescent-shaped structure or marking, especially the white area at the base of a fingernail that resembles a half-moon.
This word is a diminutive of the Latin 'luna,' moon.
