Quantum nonlinear optics: controlling few-photon interactions
… around us can be explained by classical optics since photons interact weakly with atoms. When the interaction is strong enough where one photon affects the properties of other photons, we go to the regime of quantum photon-photon nonlinear optics. The work in this thesis explores this …

Nonlinear optics for frequency-doubling in nanosatellite laser communication
In this work, we assess the utility of nonlinear optics for frequency-doubling to enable free space optical (FSO) communication links to take advantage of the ability to switch between two wavelengths using one transmit module. Our analysis shows that incorporating frequency-doubling with nonlinear …

Explanation and prediction of curious experimental phenomena in lasers and nonlinear optics
Experimental data often contains curious and unexplained results. In the course of experimental investigations of Raman shifting and the Co:MgF₂ laser, results were obtained which would not have been expected from the typical theoretical picture. In the case of Raman shifting, the forward Stokes …
