Combining Reflectometry, Ablation and Fluid Collection in a Microstructured Fiber

Abstract: The purpose of the diploma work is to investigate the possibilities to combine three different areas; reflectometry, microfluidics and laser ablation in a microstructured single-mode fiber, thus obtaining a controlled technique for positioning for ablation and collection of liquids from small inclusions. Each of the three areas is thoroughly described in different sections of this report. The first part of the experiments in this diploma work consisted of combining reflectometry and microfluidics, the second part combining reflectometry with laser ablation and the final experiment setup consisted of a combination of all three areas. An artificial system for liquid collection was then designed for that purpose. The results obtained from experiments and measurements clearly demonstrate that combining reflectometry, laser ablation and fluid collection in a single optical fiber is promising. Future work will include improvements of the technique towards a medical application for bone marrow transplantation.
