science fuses chemistry and physics to arrive at the innovative idea of using intense, ultra-short laser pulses to image and even ultimately control molecules.
Here, wavefront rotation has been induced on the laser beam, leading to a spatial splitting of this attosecond
pulse train into a collection of beamlets containing isolated attosecond
pulse, high harmonic lasers (HHG), and EUVL semiconductor source and process development too.
Drawing on our unique combination of expertise covering electron diffraction and few-cycle laser optics likewise, we will replace the photon pulses of conventional attosecond
spectroscopy with freely propagating single-electron pulses at picometer de Broglie wavelength, compressed in time by sculpted laser fields.
His vision, in 1993, led him to become a pioneer in a field called attosecond
science; since then his work has won him a stack of Canada's top science prizes.
Study leader Professor Ferenc Krausz said: "Opening the attosecond
timescale could provide new insights into the atomic world.
The laser can be used as a seed laser and integrated with an amplifier to generate intense sub-10fs pulses to broaden its applications to areas such as ultra-broad-bandwidth terahertz spectroscopy, sensing of chemical and biological warfare agents or explosives, and attosecond
These tools along with the techniques of laser-field-controlled XUV photoemission ( attosecond
streaking ) and ultrafast UV-pump/XUV-probe spectroscopy have permitted real-time observation of electronic motion in experiments performed on atoms in the gas phase and of electronic transport processes in solids.
Widely recognized for developing the world's highest precision ultrafast lasers, FEMTOLASERS enables some of the most advanced research applications, including the pioneering of attosecond
But one day, even the speedy attosecond
will fail to satisfy scientists.
This fully updated second edition is enhanced by 80% and covers the latest techniques and applications, including nanostructures, attosecond
processes, optical control of chirality, and weak and strong field quantum control.
Objective: Femtosecond laser pulses can be exploited to trace the ultrafast motion of electrons ( attosecond
physics ) and study the properties of molecules, and the changes they undergo, on the atomic scale ( femtochemistry ).
