The interaction of femtosecond laser radiation with a wavelength of 1030 nm with chalcogenide glasses of various compositions has been studied. The dependence of the optical transmission of chalcogenide glasses on the pulse energy and frequency has been experimentally established. The compositions of glasses for their use as an optical medium for laser micromachining in the infrared range have been established. It is shown that Ge7Se93 glass is the most suitable optical medium for spectral studies of diamond in the near and mid-IR range.
Исследовано взаимодействие фемтосекундных лазерных импульсов с поверхностью кварцевого стекла. В результате интерференции между падающим излучением и поверхностными плазмон-поляритонами наблюдалось образование самоорганизующихся субволновых периодических структур с периодом 250 nm. Выявлена минимальная энергия в импульсе, при которой запись происходит без абляции поверхности. Ключевые слова: прямая лазерная запись, фемтосекундные лазерные импульсы, кварц, нанорешетки.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
