Microstructure materials are currently used in different fields. One of these areas is sensor devices such as microfluidic devices. The devices are made from transparent materials such as glass and PDMS (Polydimethylsiloxane). Even though there are several techniques that are currently used to remove substance and create micro channels on material surface, laser ablation is still one of the important methods that can be used in microfabrication. This importance results from the development of laser. In the past, laser with long pulse duration (>picosecond) had been used to fabricate microstructure materials, but because pulse duration of laser was longer than thermal relaxation time of ablated material, the thermal effect was present and caused micro crackers into materials. However, after ultrafast pulse laser (pulse duration <picosecond) is generated, the micro processing of materials using this laser allows for the possibility of material removal on order of micro scale without thermal damage. In fact, manufacture of microstructure materials suing ultrafast pulse laser is still under study. Therefore, the main goal of PhD project is the investigation of the performance of ultrafast laser ablation of materials that can be used in microfluidic fabrication. The glass and PDMS will be under study in the first stage. As a part of Initial stage, laser ablation of hard tissue including and bone will be investigated by using ultrafast pulse laser.
