Researchers get the laser pulse duration of less known to date

Researchers get the laser pulse duration of less known to date

The laser , which first implementation dates from 1960, is present in the industry (welding, precision cuts, etc.), drug (eye operations) or telecommunications (thanks to the optical fiber or even outdoors) and indeed are still the basis of much from multiple disciplines and areas of expertise. If we mentioned a few weeks ago that the Lawrence Livermore National Laboratory in the United States had established a record with the most potent laser (with 500 trillion watts), a research team from the University of Central Florida has published a research article in which describe a rather unique discovery: the shortest pulse achieved to date, one just 67 attosecond pulse .

Attosecond 67?? El attosecond is a unit of time equal to one trillionth of a second, thus we can get an idea of how long it has taken so small pulse generated by the research team belonging to Area Florida Optics and Photonics. In fact, the finding of the equipment exceeds the previous high mark was at 80 attosecond.

We might be able to see the processes described quantum mechanics

A laser pulse of its kind, researchers say, may be likened to a camera flash, a glimmer with which “illuminate” a dark area to capture an image and, basically, is what could be done with this laser observe processes occurring in nature, for example, real-time observe the movement of electrons in their orbits (and to that end have had to design a receiver too “sensitive” to detect the light beam as short duration).

This finding may open a new door to a world hidden far where we could see how they move the electrons in atoms and molecules, thus following the chemical reactions that take place in these
