High-order harmonics generation in Cd and Pd laser-induced plasmas
Ganeev, Rashid A.; Kim, Vyacheslav V.; Butikova, Jelena; Atvars, Aigars; Grube, Jurgis; Sarakovskis, Anatolijs; Ubelis, Arnolds (Optica Publishing Group, 2023)We demonstrate the generation of high-order harmonics of laser pulses in palladium and cadmium plasmas. We adjusted the wavelength of driving pulses to investigate the resonance enhancement in different ranges of extreme ... -
Investigation of Nonlinear Optical Processes in Mercury Sulfide Quantum Dots
Kim, Vyacheslav V.; Shuklov, Ivan A.; Mardini, Alaa A.; Bundulis, Arturs; Zvyagin, Andrey I.; Kholany, Rawda; Lizunova, Anna A.; Grube, Jurgis; Sarakovskis, Anatolijs; Ovchinnikov, Oleg V.; Ganeev, Rashid A. (MDPI, 2022)The authors report the third-harmonic generation, nonlinear refraction, and nonlinear absorption in HgS quantum dot (QD) suspensions and films using the nanosecond and femtosecond pulses. High conversion efficiency (7 × ... -
Nonlinear absorption and refraction of picosecond and femtosecond pulses in HgTe quantum dot films
Bindulis, Arturs; Shuklov, Ivan A.; Kim, Vyacheslav V.; Mardini, Alaa A.; Grube, Jurgis; Alnis, Janis; Lizunova, Anna; Razumov, Vladimir F.; Ganeev, Rashid A. (Multidisciplinary Digital Publishing Institute (MDPI), 2021)We report measurements of the saturated intensities, saturable absorption, and nonlinear refraction in 70-nm thick films containing 4 nm HgTe quantum dots. We demonstrate strong nonlinear refraction and saturable absorption ... -
Plasma Dynamics Characterization for Improvement of Resonantly Enhanced Harmonics Generation in Indium and Tin Laser-Produced Plasmas
Kim, Vyacheslav V.; Butikova, Jelena; Grube, Jurgis; Sarakovskis, Anatolijs; Ganeev, Rashid A. (MDPI, 2022)In this study, we characterize the properties of indium and tin laser-induced plasmas responsible for efficient high-order harmonics generation of the ultrashort pulses propagating through these media. The optimally formed ... -
Variation of Nonlinear Refraction and Three-Photon Absorption of Indium–Tin Oxide Quantum Dot Thin Films and Solutions in Near Infrared Range
Bundulis, Arturs; Berzina, Anete; Kim, Vyacheslav V.; Polyakov, Boris; Novikovs, Aleksandrs; Ganeev, Rashid A. (MDPI, 2023)We characterize the nonlinear optical properties of indium–tin oxide (ITO) quantum dots (QDs) in the IR range using the Z-scan method. We present results of three-photon absorption (3PA), third harmonic generation (3HG), ...
