1. Resonance-enhanced Second Harmonic Generation from spherical microparticles in aqueous suspension
Abstract : Second harmonic generation (SHG) is a nonlinear optical effect sensitive to interfaces between materials with inversion symmetry. It is used as an effective tool for detection of the adsorption of a substance to microscopic particles, cells, liposomes, emulsions and similar structures, surface analysis and characterization of microparticles.

3. Second-generation High-Order Harmonic Sources — From CPA to OPCPA
Abstract : This thesis presents two sources of extreme ultraviolet (XUV) radiation based on high-order harmonic generation (HHG) in gases. The sources were developed for experiments requiring high-flux harmonic beams or HHG pulses at high-repetition rate. These were used experimentally to image nano-scale objects. READ MORE

4. Optimization of High-order Harmonic Generation for Attosecond Science
Abstract : High-order harmonic generation is a highly nonlinear, though inherently inefficient, process which can lead to emission of coherent, broadband extreme ultraviolet radiation in the form of attosecond pulses. Attosecond pulses are crucial for experiments investigating photoionization dynamics on the femto- and attosecond timescales. READ MORE
