Our research interest is focused on understanding the light-matter interaction process with intense femtosecond laser pulses and the applications to pioneering new fields of photon energy technology. We are challenging to material control in nanometer-scale size. We have reported the first evidence of excitation of surface plasmon polaritons on nonmetallic materials with intense femtosecond (fs) laser pulses, as the intense fs laser pulse produces a high density of free electrons to form a metal-like layer on the surfaces. The experimental results have demonstrated the generation of enhanced near fields for the periodic ablation of the surfaces. The near-fields of SPPs excited with intense fs laser pulses can sculpt homogeneous periodic nanostructures on the materials. Based on the physical model proposed, our goal is development of novel technique for laser material nanoprocessing.
The TUAT Tenure Track Program is excellent for quickly building-up of new laboratory, because it gives me the big financial support, and provides me abating instruction and other works in the university. This program also offers me much opportunity for communicating with many tenured teachers to hold much their experience and knowledge. As a result, I was able to build up my laboratory without hesitation. If this program such as the TUAT Tenure Track Program is expanded to all over the country, the education and research systems in the university are expected to be changed.
Material science with ultrashort laser pulses is very interesting field, because there is much physical mechanism to be clarified and it can be applied to industrial technology. Through my research outcomes, I would like to play a key role of making a common foundation in various kinds of fields for science and technology.
