My research in past several years has focused mainly on laser-material processing, laser damage, ultrafast beam engineering, and ultrafast dynamics.

My key achievements in the field:
1) Localization of the light well below the diffraction limit (sub-micron scales) in dielectrics.
2) Ultrafast laser induced 3-D nano structuring in bulk dielectrics.
3) Ultrafast imaging of nano structuring and free carrier dynamics on the formation of positive and negative index structures formation.
4) Study of laser-induced damage threshold (LIDT) of various optical components for ELI's petawatt class lasers.
5) Development of two color/single color pump-probe microscopy.
6) Development of high vacuum LIDT test station.
7) Optical and structural surface cleanliness and verification.
