Invited Speaker / Conférencier invité

Applications development using terahertz technology has seen exponential growth in recent years, thanks in part to the availability of inexpensive, tabletop systems. One of the unique aspects of THz technology is that it exploits coherent detection to map the electric field directly in time, allowing researchers to probe dynamics on the picosecond time-scale, referred to as THz Time-Domain...

Using the 100Hz line of the ALLS laboratory (Varennes, QC) we achieved 1.8$\mu$m central wavelength two-cycle pulses with an energy per pulse of more than 4mJ. High energy amplification of a white light OPA output and propagation through a noble gas filled 2m hollow core fiber were needed to obtained this high gain in output energy compared to what was previously achieved for ultrashort...

393. Exploring nanoscale ultrafast dynamics in semiconductors with terahertz-STM

Invited Speaker / Conférencier invité

The ability to spatially resolve ultrafast phenomena over nanometer length scales is essential for understanding nanoscale excitation dynamics in materials as well as for measuring switching speeds of nanodevices. The scanning tunneling microscope (STM) uses quantum tunneling of electrons between a scanning tip and a sample to achieve nanoscale imaging of surfaces with atomic resolution....

160. Parallel MicPIC for first-principle analysis of light-matter interactions in solids

Oral (Non-Student) / orale (non-étudiant)

One of the main challenges in modeling laser-driven plasma physics is to properly resolve microscopic and macroscopic phenomena at the same time. For example, to resolve the propagation of a near-infrared pulse in a solid-density plasma, it is necessary to cover about four to five orders of magnitude in space---from angstrom to micron---to resolve both the atomic collision processes and light...
