Second harmonic generation (SHG) is a non-linear optical process where two photons from the pump wave interacting with a non-linear material are combined to generate a new photon, with twice the frequency of the initial ones. The use of organic crystals for SHG is appealing, as the nonlinear coefficients of these crystals are much greater than those of standard inorganic materials, especially...
Laser-induced breakdown spectroscopy (LIBS) is an elemental analysis technique in which a high powered laser is used to create a plasma on the surface of a sample. The light emitted from this plasma through a de-excitation process is then collected and used to spectrally analyze the sample. Two techniques that can improve the signal-to-noise ratio of LIBS spectra are dual-pulse LIBS, which...
Dissociative excitation of adenine (C5H5N5) into excited atomic fragments has been studied in the electron impact energy range from threshold to 400 eV. A crossed beam system coupled to a vacuum ultraviolet (VUV) monochromator is used to study emissions in the wavelength range from 90 to 200 nm. The beam of adenine vapor from a stainless steel oven is crossed at right angles by the electron...
Pyrrole and furan, two aromatic five-membered ring molecules, have been the subject of extensive ab initio and experimental studies. We have taken Fourier transform far-infrared spectra of these molecules at the Canadian Light Source. Two fully-entangled vibrational bands of furan, n8 and n21 at ~ 870 and 873 cm-1, that are present in the spectra show some perturbations and interact with each...
Radiative transition probabilities in atoms are normally calculated from
nonrelativistic wave functions and the electric dipole transition operator.
The theory of relativistic corrections to nonrelativistic energies is
well established in terms of the Breit interaction, but the same is not
true for relativistic corrections to transition probabilities.
Our objectives are first, to start from...
Integrity of digital security is crucial for maintaining the secrecy of banking data, personal information, company trade secrets, governmental records, and more. A perfectly implemented quantum cryptographic scheme, such as quantum key distribution (QKD), would be impossible to break. Freespace QKD systems commonly rely on polarization encoded single-photons. However, the optics required to...
Il s’agit de concevoir et de fabriquer un laser à l’état solide aux dimensions réduites pouvant émettre dans un seul mode aux hautes puissances. Nous fabriquons nos miroirs lasers polarisants en déposant sur un miroir laser commercial une couche anisotrope servant de lame quart d'onde par la méthode de déposition par incidence oblique. Le matériau utilisé est le dioxyde de titane. Une...
An exciting frontier in quantum information science is the realization of complex many-body systems whose interactions are designed quanta by quanta. Hybrid nanophotonic system with cold atoms has emerged as the paradigmatic platform for engineering long-range spin models from the bottom up with unprecedented complexities. Here, we develop a toolbox for realizing fully programmable complex...
