Obiettivo This project is aimed at the development and experimental demonstration of fibre-optic solutions for the delivery and spectral transformation of high-power ultra short laser pulses based on the fibres of a new type -- hollow-core photonic-crystal fibres. Fundamental aspects of the proposed research will include the investigation of wave guiding due to photonic band gaps, analysis of the properties of air-guided modes in photonic-crystal fibres, and the study of the influence of ionisation and plasma-formation effects on the guided-wave propagation of high-intensity ultra short laser pulses in hollow-core fibres. Applied aspects and the exploitation plan include the use of hollow-core photonic-crystal fibres developed as a result of this project to guide high-power laser pulses for laser-ablation, micro machining, and biomedical applications, as well as to improve the sensitivity of non-linear-optical spectroscopy on the gas phase. Hollow-core photonic-crystal fibres for the transportation of high-power ultra short laser pulses will be designed and fabricated. The ways to enhance non-linear-optical processes, including wave mixing and harmonic generation, in gas-filled hollow-core photonic-crystal fibres will be explored. The influence of ionisation and plasma-formation effects on the propagation and non-linear-optical interactions of high-power ultra short pulses in hollow-core fibres will be theoretically analysed and experimentally investigated. The potential of hollow-core photonic-crystal fibres capable of transporting high-power ultra short laser pulses for laser-ablation technologies, micro machining, and biomedical applications will be demonstrated as a part of the work under this project. The project will include all the phases of investigations from the design of microstructure and photonic-crystal fibres through their fabrication, characterisation, and testing to the experimental work and real-life applications. The methodology of research will thus include fibre design, fibre characterisation, analysis of wave guiding and dispersion properties of the fibre, experiments on short pulse, propagation, non-linear-optical experiments, and applications. The feedback loop will be closed as the results of experiments and applications will be used as new entries for the design stage, allowing fibre characteristics to be improved and fibres to be adapted for real-life applications. All the main ingredients of this research methodology have been tested in preliminary work by research teams involved in the project. This is the first time, however, that all these methodologies will be put together, which becomes possible due to the combination of expertise and the complementary nature of research teams involved in the project and the coherent use of laser and fibre-drawing facilities, as well as computer resources and previously developed theoretical approaches and computer codes, which makes this project an intrinsically collaborative effort.
