Application of Femtosecond lasers in confocal and scanning tunnelling microscopy
… induce DNA damage in the nuclei of live cells by multi-photon absorption, the development and comparison of foci counting algorithms for the quantitative assessment of radiation damage and work towards the development of an ultrafast Scanning Tunnelling Microscopy (STM) technique, employing a …

Plasmon Directed Chemical Reactivity and Nanoparticle Self-Assembly
… pulsed 750 nm laser light, making use of multi-photon absorption. Both methods of self-assembly, as well as the secondary photoreaction, are dependent on the plasmonics of the metal nanoparticles. This thesis also goes into the backgrounds of plasmonics, plasmonically mediated catalysis, …

Three-photon Absorption Process In Organic Dyes Enhanced By Surface Plasmon Resonance
Multi-photon absorption processes have received significant attention from the scientific community during the last decade, mainly because of their potential applications in optical limiting, data storage and biomedical fields. Perhaps, one of the most investigated processes studied so far has been …

Towards multiple quantum well optically pumped far infrared lasers
Optically pumped lasers based on GaAs/AlGaAs multiple quantum well (MQW) structures are a potential coherent source in the far infrared (FIR) wavelengths. The FIR (~ 30 to 300 µm) is a region within the electromagnetic spectrum that has seen relatively little development. No practical solid-state …

… laser pulses have enough intensity to create multi-photon absorption, and they do not induce plasmoid interactions, which makes the patterning much easier to control. The interaction of multiple coherent light beams can produce a variety of periodic structures whose shape and period depend on …

Materials and processes for the optical additive manufacturing of advanced organic/inorganic nanocomposites for the mask-less plating of insulator and semiconductor substrates, and microfluidic devices
… This technique exploits the optical, nonlinear multiphoton absorption process, and allows for the fabrication of 3D objects featuring details below the diffraction limit, down to 100 nm or even less. Here, this multi-photon absorption process is exploited to trigger the photo-reduction of the …
