N
ovel laser based methods are currently a hot subject of research as an alternative path towards development of
nanostructures in bulk materials and on surfaces of materials. The subject of the ongoing research is the phenomena
taking place during laser surface interaction and the potential in creating structures which may give additional
functionalities to the material surface. The use of ultra fast lasers with temporally shaped pulses has been a novel
methodology in the exploration of the potential in creating novel nano structures that could not have been accessed
with traditional laser irradiation of surfaces. In this presentation, author will review the work of his group where he has
demonstrated the employment of temporally shaped laser pulses to finely tune tweak the surface morphology (i.e., the
grown nanostructures and their characteristics) through a non standard interaction of the incident laser pulses with the
irradiated surface. This is a result of numerous fundamental physical processes ranging from the femtosecond to the
nanosecond temporal window and are triggered by the temporal regulation of the energy deposition of the laser energy
onto the under study surface. The manifestation through the creation of laser induced periodic surface nano-structures
and the tuning of their morphological characteristics, e.g., spatial frequency and contrast will be the central part of the
discussion. Further, he reviews work on applying time resolved pump prove laser spectroscopy in order to characterize
and study the modified ultra fast electronic phenomena and interactions that take place on nano structured surfaces,
reduced dimensionality quasi two dimensinal systems and more complex three dimensional metallic nanostructures.
