Abstract: In the presented research, I have undertaken the problem of femtosecond laser interactions with matter, under various laser pulse parameters and considering a wide group of materials, i.e. metals, plastics, graphene, silicon. There is a considerable interest in the precise material micro and nanomachining with ultrashort laser pulses. It is well established, that the quality of ablation process with femtosecond laser is much better than when using long pulse lasers. The use of femtosecond laser pulses creates an attractive opportunity for high quality micromachining of many groups of materials and opens an interesting field in fundamental research. The objective of the fundamental research proposed within this research is a complex study of the physical phenomena occurring during short-pulsed (femtosecond) laser interactions with matter. Although the research topic itself is very popular in the scientific community, it is relatively little elucidated. A better examination of the effec ts of electromagnetic irradiation on the materials in the femtosecond regime will provide a better understanding of the subject. The experimental results obtained from this project and theoretical considerations will provide a verification of the existing theories on laser-matter interactions. Additionally, the experimental investigations will be carried out on novel materials, i.e. graphene. I have specifically taken under investigation the laser ablation phenomena, which occurs during a highly energetic laser irradiation of the material and results in detachment of microparticles from the material. The physics of the ablation process in an ultrashort laser pulses regime differs from the ablation caused by the long (nanosecond and picoseconds) laser pulses. The nature of the process is more complex with the short pulses and the complete, research based understanding of the phenomena is not available yet. (More)
