| Summary: | Ultrafast laser has become central of attraction ever since more and more applications of these pulse trains were being disclosed. Mode-locking of laser could be done to achieve ultrafast laser. Fabrication methods of saturable absorber for the purpose of passive mode-locking are being explored from time to time, for there is no one best method is found yet for high performance, cost effective, time-efficient and at the same time high yield production of saturable absorber. Environmental impacts it brought to the society should also be taken into consideration too during the fabrication process. In the project, the student has fabricated two types of saturable absorber, which include Molybdenum disulphide and Graphite which could further be classified into powder and flake form. Characterization of these saturable absorbers has been carried out to compare the production quality and their performance when they are integrated into the cavity of Yb-doped fiber ring laser system. Based on the results obtained, the student has also made detailed analysis and given possible future ventures on this topic. |
