Sentences with phrase «using ultrafast laser»

Using ultrafast laser pulses that speed up the data recording process, Caltech researchers adopted a novel technique, ultrafast electron crystallography (UEC), to visualize directly in four dimensions the changing atomic configurations of the materials undergoing the phase changes.

«By using ultrafast lasers, which are very intense but very short in duration (of the order of a billion trillion flashes per second), we have realized a world record in optical quality, where all the obtained shaped particles behave like nano - sized clones,» explains Andrés Guerrero Martínez, researcher of the Ramón y Cajal Program at the Faculty of Chemical Sciences of the UCM.

Using ultrafast lasers, they found that the interaction between the sun's energy and the chlorophyll molecules in a bacterium relies on a piece of quantum mechanical weirdness known as superposition, where a single photon's energy can temporarily be in many different states at once.

The new multimodal imaging probe uses an ultrafast laser to create nonlinear optical effects in tissue that can reveal cancer and other diseases.

This novel, less invasive way of detecting disease using light salient properties was employed for the first time in 1991 to identify a fingerprint for cancer in tissue by a team led by Robert Alfano, a Distinguished Professor of Science and Engineering at The City College of New York, and director of The Institute for Ultrafast Spectroscopy and Lasers (IUSL) of the City University of New York at City College.

In a combined experimental and theoretical study on ultrafast excitation of atoms in intense short pulse laser fields scientists of the Max Born Institute succeeded to show that the prevailing and seemingly disparate intuitive pictures usually used to describe interaction of atoms with intense laser fields can be ascribed to a single nonlinear process.

There are tradeoffs in using X-rays vs. electrons to study ultrafast processes at ultrasmall scales, he noted, though «even if the capabilities are similar, it's worth pursuing» because of the smaller size and lesser cost of machines like APEX and HiRES compared to X-ray free - electron lasers.
