This Request for Proposal is an invitation by the University of Ottawa to prospective proponents to submit proposals for the provision of a laser system including one pump laser and one continues wave (CW) Ti-Sapphire tunable laser. A complete laser system, consisting of a pump laser, a CW Ti:Sapphire tunable laser (Ti:Sa laser), and all requisite optics, control electronics, cooling, and software needed for operation must be provided.
This instrument system provides a tunable coherent light source with narrow linewidth, single frequency emission to perform high-resolution laser spectroscopy on nanostructured semiconductors. Laser spectroscopy has led to extraordinary advances in the precision with which spectral lines can be measured, and this has crucial significance for our understanding of fundamental light-matter interactions. This laser system will allow for measurements including (i) photoluminescence, (ii) Raman spectroscopy, (iii) reflectance, (iv) resonant fluorescence, and (v) near-field coupling. These examples represent only a small selection of the many possible techniques by which spectroscopy provides tools to explore matter at the nanoscale. The amount of information that can be extracted from a spectrum depends critically on the stability, tunability, and linewidth of the laser emission. This research will elucidate the fundamental mechanisms underlying light-matter interaction in semiconductors coupled to nanophotonic structures such as layered transition metal dichalcogenides (and their related heterostructures) coupled to nanophotonic structures. The results generated by the program can pave the way for transformative optoelectronic devices.
