Sentences with phrase «powerful laser pulses»

By irradiating oriented molecules with powerful laser pulses, the researchers were able to obtain high - harmonic spectra reflecting the state of a molecule's electron shell.

So far, this drastic increase in speed takes about 5 to 10 minutes to trigger with the 150 - watt mercury lamp the researchers used, but Leigh says more powerful laser pulses could set off turbo boosts in a microsecond or less.

NIF, in contrast, takes a tiny capsule filled with hydrogen fuel and crushes it with a powerful laser pulse.

In their experiments, the group fired a powerful laser pulse at a micrometer - sized plastic sphere, blasting a bunch of protons from the target and accelerating them to velocities approaching the speed of light.

«In reality we are observing not the position of the electrons, but rather the high - harmonic spectrum which occurs during the process of interaction between a powerful laser pulse and a molecule.

Not exact matches

One key to the microscope's success is its powerful 2 - photon laser, which emits pulses that probe up to 300 microns deep into the brain.

When exposed to pulsed laser light, the gold evaporated, producing a powerful shock wave in the colloid comparable to that caused, say, by the impact of a micrometeorite.

Conventional wisdom holds that many smaller lasers, combined in a particular way, could essentially create one ultra powerful pulse.

To move on to other atoms and molecules will require more powerful lasers with shorter pulses, of the type used in coherent control chemistry, so the future of this method is very promising.»

The problem, however, is creating a laser pulse that's powerful enough to compete with the big accelerators.

The researchers fixed a three centimetre long diamond strip, just 0.3 millimetre thick, in a specimen holder and triggered a shock wave with a brief flash from a powerful infrared laser that hit the narrow edge of the diamond; this pulse lasted 0.15 billionths of a second (150 picoseconds) and reached a power level of up to 12 trillion watts (12 terawatts) per square centimetre.

Those technologies include the «driver» used to crush the fuel capsule, such as lasers, heavy ion beams, or powerful pulses of electric current.

Along with the change of laser size, the researchers also adjusted the magnetic material through which the light travels and amplifies to a more powerful pulse.

The 3.4 km long European XFEL is the largest and most powerful of the five X-ray lasers worldwide, with the ability to generate the short pulses of hard X-ray light.

Under the effect of powerful and very short laser pulses, the molecule's electron shell configuration changed: a «hole» appeared — a shell vacancy which then began to oscillate moving from one end of the molecule to the other.
