Application of Quasi-Phase Matching Concept for Enhancement of High-Order Harmonics of Ultrashort Laser Pulses in Plasmas
Ganeev, Rashid; Stremoukhov, Sergey; Andreev, A. V.; Alnaser, Ali (MDPI, 2019)Novel methods of coherent short-wavelength sources generation require thorough analysis for their further amendments and practical implementations. In this work, we report on the quasi-phase matching (QPM) of high-order ... -
Enhancement of the corrosion resistance of mild steel with femtosecond laser- nanostructuring and CrCoNi medium entropy alloy coating
Ahmad, Shahbaz; Ahmad, Waqas; Abu Baker, Aya; Egilmez, Mehmet; Abuzaid, Wael; Orhan, Mehmet Fatih; Ibrahim, Taleb; Khamis, Mustafa; Alnaser, Ali (Elsevier, 2022)In this work, the corrosion resistance of mild steel surface nanostructured with a femtosecond laser and coated with high corrosion resistant CrCoNi (CCN) medium entropy alloy through magnetron sputtering is studied. ... -
Few-cycle laser driven reaction nanoscopy on aerosolized silica nanoparticles
Rupp, Philipp; Burger, Christian; Kling, Nora G.; Kübel, Matthias; Mitra, Sambit; Rosenberger, Philipp; Weatherby, Thomas; Saito, Nariyuki; Itatani, Jiro; Alnaser, Ali; Raschke, Markus B.; Rühl, Eckart; Schlander, Annika; Gallei, Markus; Seiffert, Lennart; Fennel, Thomas; Bergues, Boris; Kling, Matthias F. (Springer Nature, 2019)Nanoparticles offer unique properties as photocatalysts with large surface areas. Under irradiation with light, the associated near-fields can induce, enhance, and control molecular adsorbate reactions on the nanoscale. ... -
Influence of gas environment on the dynamics of wetting transition of laser-textured stainless steel meshes
Kim, V. V.; Yalishev, V. S.; Khan, S. A.; Iqbal, Muhammad; Boltaev, G. S.; Ganeev, Rashid; Alnaser, Ali (American Institute of Physics Inc., 2021)We analyze the role of surrounding gas and aging in ambient air in the wettability behavior of laser-processed stainless steel meshes. Laser texturing of meshes was carried out in the presence of different gases (N₂, O₂, ... -
Recent Advances in Femtosecond Laser-Induced Surface Structuring for Oil–Water Separation
Alnaser, Ali; Khan, Sharjeel Ahmed; Ganeev, Rashid; Stratakis, Emmanuel (MDPI, 2019)Femtosecond (FS) laser-induced surface structuring is a robust, maskless, non-contact, and single-step process for producing micro- and nanoscale structures on a material’s surface, which remarkably alters the optical, ...
