Formation of microspheres under the action of femtosecond laser radiation on titanium samples in hydrocarbons

Процессы Абляции И Роста Структур При Воздействии Фемтосекундных Лазерных Импульсов На Поверхность Галлия В Среде Аммиака

“…> 10 −10 s) приводит к увеличению области нагрева за счет теплопроводности материала и интенсивного нагрева лазерным эрозионным факелом [12][13][14]. Лазерная абляция материала в реакционной среде обеспечивает возможность формирования химической связи аблируемого материала и компонентов среды, в том числе возможно получение оболочечных частиц [15][16][17][18].…”

Processes of ablation and structures growth under the action of femtosecond laser pulses on the gallium surface in an ammonia medium

“…> 10 −10 s) leads to an increase in the heating area due to the thermal conductivity of the material and intense heating by the erosion laser torch [12][13][14]. Laser ablation of a material in a reaction medium makes it possible to form a chemical bond between the ablated material and the components of the medium, including the possibility of obtaining shell particles [15][16][17][18].…”

Investigation of material heating under the action of ultrashort laser pulses

“…Currently, the process of laser ablation of materials when exposed to ultrashort pulses is of great scientific and practical interest [1][2][3]. In the process of laser ablation processing, including in liquid media, it is possible not only to process the surface of materials, but also to synthesize nanoscale materials with predictable dispersion [4,5].…”

“…Ablative laser synthesis of nanoparticles makes it possible to obtain spherical granules with a narrow granulometric composition [1,3,11]. However, this method also has a number of disadvantages, namely, the synthesized particles can have traces of fusion, together with the main material at the outlet, traces of "splashes" can be observing, and there can be pronouncing traces of the presence of a melt pool [12][13][14][15].…”
