The writing process of birefringent structures in the volume of fused silica by focused ultrashort laser pulses with wavelength in visible range and various values of pulse energy, pulse duration, repetition rate, numerical aperture and moving substrate velocity has been studied. The retardance value of fabricated structures has been measured and influence of the subsequent annealing of these structures has been studied. It was shown, that combination of writing layered structures with subsequent annealing provides structures with high homogeneity, required retardance value and high transmittance.
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.
