Laser synthesis of polyyne molecules C2nH2 (n > 2) in liquid hydrocarbons is a complex process in which intense pulsed radiation decomposes the initial carbon-containing substance (the hydrocarbon solvent itself or the solid carbon particles in a sus

The propagation of graphitization wave through the diamond bulk under multipulse laser irradiation is a largely self-guided process. This fact assists the production of graphitized wires oriented along a laser beam and greatly complicates formation o

The dynamics of the optical properties of water bulk exposed to femtosecond radiation (Ti-sapphire laser, wavelength 800 nm, intensity ∼ 10 13 W / c m 2 ) was studied in the time window of ≈ 1.5 n s using a pump–probe technique. Both the refrac

Structural modifications of tetrahedral amorphous carbon (ta-C) films, caused by single-pulse laser irradiation, were investigated. Graphitization of the films, content and size of sp2 carbon clusters were analyzed by means of Raman spectroscopy. It
