Abstract:Magistrsko delo opisuje sistem za obdelovanje optičnih vlaken in steklenih kapilar, ki je bil izdelan kot razširitev že obstoječega fs laserskega sistema. Opisana sta metoda pridobivanja ultrakratkih laserskih sunkov in teoretično ozadje njihove interakcije z obdelovanim materialom. Nadalje je obravnavan postopek izdelave senzorjev, ki uporabljajo odprto mikrocelico, izdelano iz steklene kapilare na obdelovalnem sistemu. Podani so spektralni odzivi izdelanih senzorjev in rezultati meritev njihovih mehanskih lastnosti. Predstavljeni so mikrofluidni kanali, mikrovijaki in mikroresonatorji, ki so bili izdelani na vrhu optičnega vlakna. Prav tako smo opozorili na zmožnost vpisovanja zrcal v jedro optičnega vlakna s fs laserjem s povzročanjem lokalne spremembe lomnega količnika. Izmerjene so bile optične in mehanske lastnosti vpisanih zrcal pri različnih energijah ultrakratkih sunkov in pri različnih konfiguracijah zrcal. Predstavljena sta bila dva primera uporabe vpisanih zrcal v praktičnih primerih.

Title:Femtosecond laser fabrication of microstructures
Abstract:In this master thesis a system for all-fiber micro-cell manufacturing is presented. System was built around an already existing fs laser system. Thesis describes an ultrashort pulse generation method and the theoretical background of ultrashort pulse and material intercation. A procedure for sensor manufacturing is presented. Sensor's spectral responses and mechanical propreties are presented. The fabrication of microfluidic channels, microscrews and microresonators on the tip of the optical fiber is described. The thesis also incorporates in-fiber mirror fabrication with ultrashort laser pulses inducing local refractive index changes. Mirror inscription took place at different pulse energy levels and in different configurations of mirror allignment. Optical and mechanical propreties of the inscribed mirrors were measured. Two application examples were shown using inscribed mirrors.
Keywords:Ultrashort pulses, femtosecond laser, micro-structres, mirror inscription, micro-cell
