碩士 === 國立臺灣科技大學 === 機械工程系 === 99 === This study aims to fabricate inner optical components by femtosecond laser. Femtosecond laser is characterized with ultra-short pulse and high fluence. And with the unique mechanism of photochemical peeling, femtosecond laser has advantages of small heat-affected zone, high precision, and low thermal stress. Therefore, optical components inside transparent materials can be manufactured precisely. In contrast with the exterior structure of optical components, the inner structure inside transparent materials by femtosecond laser sustain abrasion and have better space utilization, which is suitable for manufacturing compound optical components. This study has successfully fabricated light-converging optical components in PMMA. And with incorporation of optical simulation, the components has calibrated and verified. Finally, comparisons between simulations and experiments have been done.
