Synthesis and low-order optical nonlinearities of colloidal HgSe quantum dots in the visible and near infrared ranges
(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 ...
Influence of gas environment on the dynamics of wetting transition of laser-textured stainless steel meshes
(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
(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, ...
Application of Quasi-Phase Matching Concept for Enhancement of High-Order Harmonics of Ultrashort Laser Pulses in Plasmas
(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 ...
