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 ... -
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, ... -
Synthesis and low-order optical nonlinearities of colloidal HgSe quantum dots in the visible and near infrared ranges
Ganeev, Rashid; Shuklov, Ivan A.; Zvyagin, Andrey I.; Dyomkin, Dmitry V.; Smirnov, Michail S.; Ovchinnikov, Oleg V.; Lizunova, Anna A.; Perepukhov, Alexander M.; Popov, Victor S.; Razumov, Vladimir F. (Optical Society of America, 2021)We synthesize colloidal HgSe quantum dots and characterize their nonlinear refraction and nonlinear absorption using a Nd:YAG laser and its second harmonic. The 7.5 nm quantum dots were synthesized using the hot-injection ...
